What Happens to the Climate When Earth Passes Through Interstellar Clouds?

Universe Today - Mon, 09/23/2024 - 7:29pm

Noctilucent clouds were once thought to be a fairly modern phenomenon. A team of researcher have recently calculated that Earth and the entire Solar System may well have passed through two dense interstellar clouds causing global noctilucent clouds that may have driven an ice age. The event is thought to have happened 7 million years ago and would have compressed the heliosphere, exposing Earth to the interstellar medium. 

Interstellar clouds are vast regions of gas and dust that flat between the stars inside galaxies. They are mostly made up of hydrogen along with a little helium and trace elements of heavier elements. They are a key part of the life circle of stars providing the materials for new stars to be formed and are seeded with elements after stars die. The clouds vary significantly in size, density and location and are an important part of the evolution of the Galaxy.

Earth’s journey around the Galaxy is not for the impatient for it takes about 250 million years to complete one full orbit at a speed of 828,000 kilometres per hour. Currently the Solar System is located in the Orion Arm, one of the spiral arms of our Galaxy. During the journey, Earth travels through different regions, encountering stars and different densities of the interstellar medium. It experiences gravitational interactions with nearby stars and nebula sometimes exerting  subtle interactions. Regardless of the immense journey, the stars of our Galaxy remain relatively unchanged over a human lifetime.

A team of astronomers let by Jess A. Miller from the Department of Astronomy of Boston University have traced the path of the Sun back through time. In doing so, they have identified two occasions when the Earth and Solar System passed through two dense interstellar clouds. One of the crossings occurred 2 million years ago, the other 7 million years ago. Exploring the properties of the clouds, the team assert that the clouds are dense enough that they could compress the solar wind to inside the orbit of Earth. 

The Solar Wind is a constant stream of charged particles, mostly electrons and protons that are emitted from the upper layer of the Sun’s atmosphere, the corona. The particles travel through the Solar System at speeds between 400 and 800 kilometres per second. The edge of our Solar System is defined as the point where the solar wind merges with the interstellar medium.

Previous teams have analysed climate change events due to these interstellar medium interactions with similar findings. Global cooling has been the result with an ice age being triggered. The study by Miller and team have readdressed this very topic using modern technology and processes. 

The team find that the interactions have indeed played a part in changes to the atmosphere of Earth. They find that levels of hydrogen in the upper atmosphere would have increased substantially. The newly acquired hydrogen would be converted to water molecules in the lower atmosphere and it would also have led to a reduction in mesospheric levels of ozone. These processes would have led to the appearance of global noctilucent clouds in the mesosphere. They would not have been permanent but may have blocked 7% of sunlight from reaching Earth, plunging our planet into an ice age.

New Video Series Spotlights Engineers on NASA’s Europa Clipper Mission

NASA - Breaking News - Mon, 09/23/2024 - 5:40pm
Learn about some of the engineering work being done by five members of NASA’s Europa Clipper mission, which aims to launch Thursday, Oct. 10.NASA

With NASA’s Europa Clipper just weeks away from launch, five short videos give a behind-the-scenes peek at some of the engineers dedicated to making the mission a success.

What does it take to build a massive spacecraft that will seek to determine if a mysterious moon has the right ingredients for life? Find out in a new video series called “Behind the Spacecraft,” which offers behind-the-scenes glimpses into the roles of five engineers working on NASA’s Europa Clipper mission, from building the spacecraft’s communications systems to putting it through rigorous tests so the orbiter can meet its science goals in space.

With its launch period opening Thursday, Oct. 10, Europa Clipper is the agency’s first mission dedicated to exploring an ocean world beyond Earth. The spacecraft will travel 1.8 billion miles (2.9 billion kilometers) to the Jupiter system, where it will investigate the gas giant’s moon Europa, which scientists believe contains a global saltwater ocean beneath its icy shell.

The videos are being released here weekly. The first two are already out.

Meet the team:

  • Dipak Srinivasan, lead communications systems engineer at the Johns Hopkins Applied Physics Laboratory, makes sure the Europa Clipper team can communicate with the spacecraft. Learn more about his work in the video above.
  • Sarah Elizabeth McCandless, navigation engineer at NASA’s Jet Propulsion Laboratory, helped plan Europa Clipper’s trajectory, ensuring the spacecraft arrives at Jupiter safely and has a path to fly by Europa dozens of times. Learn more about Sarah’s work here.
  • Jenny Kampmeier, a science systems engineer at JPL, acts as an interface between mission scientists and engineers.
  • Andres Rivera, a systems engineer at JPL and first-generation American, works on Europa Clipper’s cruise phase — the journey from Earth to Jupiter.
  • Valeria Salazar, an integration and test engineer at JPL who spent her childhood in Mexico, helped test the Europa Clipper spacecraft to ensure its launch readiness.
Upcoming Livestreams and Broadcasts

Europa Clipper experts will answer questions about the mission in a NASA Science Live show airing in English on Tuesday, Oct. 1, and in Spanish on Thursday, Oct. 3. The broadcasts will appear on NASA+, YouTube, Facebook, and X. The Spanish broadcast will be streamed on the NASA en Español YouTube channel. Viewers can submit questions on social media using the hashtag #askNASA or by leaving a comment in the chat section of the Facebook or YouTube stream.

Europa Clipper is the largest spacecraft NASA has ever developed for a planetary mission and will fly through the most punishing radiation environment of any planet in the solar system. The spacecraft will orbit Jupiter and, during multiple flybys of Europa, will collect a wealth of scientific data with nine science instruments and an experiment that uses its telecommunications system to gather gravity data.

More About Europa Clipper

Managed by Caltech in Pasadena, California, JPL leads the development of the Europa Clipper mission in partnership with the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, for NASA’s Science Mission Directorate in Washington. The main spacecraft body was designed by APL in collaboration with JPL and NASA’s Goddard Space Flight Center in Greenbelt, Maryland. The Planetary Missions Program Office at NASA’s Marshall Space Flight Center in Huntsville, Alabama, executes program management of the Europa Clipper mission.

From Frozen to Sweltering: Earth’s Climate Over the Last 485 Million Years

Universe Today - Mon, 09/23/2024 - 5:14pm

Earth’s last half-billion years were action-packed. During that time, the climate underwent many changes. There have been changes in ocean levels and ice sheets, changes in the atmosphere’s composition, changes in ocean chemistry, and ongoing biological evolution punctuated with extinction events.

A record of Earth’s temperature over the last 485 million years is helping scientists understand how it all played out and illustrating what could happen if we continue to enrich the atmosphere with carbon.

The new temperature record is presented in research titled “A 485-million-year history of Earth’s surface temperature.” It’s published in Science, and the lead author is Emily Judd. Judd is from the Department of Paleobiology at the Smithsonian National Museum of Natural History.

“This research illustrates clearly that carbon dioxide is the dominant control on global temperatures across geological time.”

Jessica Tierney, University of Arizona

The new historical temperature comes from an effort named PhanDA, which stands for Phanerozoic Data Assimilation. PhanDA combined data from climate models with data from geology to determine how the climate has changed over the last nearly 500 million years. The Phanerozoic is Earth’s current geological eon, and it started 538.8 million years ago. It’s known for the proliferation of life, and its beginning is marked by the appearance of the hard shells of animals in the fossil record.

PhanDA is a mix of data and prior simulations by the scientific community. “This approach leverages the strengths of both proxies and models as sources of information, providing an innovative way to explore the temporal and spatial patterns in Earth’s climate across the Phanerozoic,” the researchers write in their paper. It allowed the researchers to reconstruct the climate more thoroughly.

This figure illustrates the data used to create PhanDA. A shows the temporal distribution of proxy data used in PhanDA. B shows the spatial distribution. C shows the range (gray band) and median (black line) of GMSTs within the prior model ensemble for each assimilated stage. Image Credit: Judd et al. 2024.

“This method was originally developed for weather forecasting,” said Judd. “Instead of using it to forecast future weather, here we’re using it to hindcast ancient climates.”

We’re blowing by atmospheric carbon benchmarks, and the Earth is warming. We’re now at over 420 ppm of CO2. The best way to understand what’s coming our way is by looking at the past.

“If you’re studying the past couple of million years, you won’t find anything that looks like what we expect in 2100 or 2500,” said co-author Scott Wing, the curator of paleobotany at the National Museum of Natural History. Wing’s research focuses on the Paleocene–Eocene Thermal Maximum, a period of dramatic global warming 55 million years ago. “You need to go back even further to periods when the Earth was really warm, because that’s the only way we’re going to get a better understanding of how the climate might change in the future.”

During the Paleocene-Eocene Thermal Maximum (PETM), a massive amount of carbon was emitted into the atmosphere and the oceans. The Earth’s temperature reacted swiftly, warming by between five and eight degrees Celsius in only a few thousand years. While a few thousand years might seem long compared to a human lifetime, it’s nearly instantaneous for the climate of an entire planet. It likely triggered the massive extinction of between 35% to 50% of benthic life. Fossils show that during this time, sub-tropical planets grew in the polar regions.

Many scientists think the PETM is the best analogue for what we’re facing today. No matter what we do with our emissions in the next several decades, much of the carbon humanity has released into the atmosphere since the Industrial Revolution will persist in the atmosphere for thousands of years.

Blue rectangles show the maximum latitudinal ice extent, and orange dashed lines show the timing of the five major mass extinctions of the Phanerozoic.

PhanDA illustrates the unbreakable link between carbon and global warming. According to co-author Jessica Tierney, a paleoclimatologist at the University of Arizona, the link between the climate and carbon is undeniable. “This research illustrates clearly that carbon dioxide is the dominant control on global temperatures across geological time,” said Tierney. “When CO2 is low, the temperature is cold; when CO2 is high, the temperature is warm.”

While proof of the link between climate and carbon isn’t new, this long timeframe drives it home. “The consistency of this relationship is surprising because, on this timescale, we expect solar luminosity to influence climate,” the authors write. “We hypothesize that changes in planetary albedo and other greenhouse gases (e.g., methane) helped compensate for the increasing solar luminosity through time.”

Overall, Earth’s global mean surface temperature (GMST) ranged from 11° to 36°C during the Phanerozoic, a larger range than previously thought. It also shows that greenhouse climates were hotter than thought. The largest temperature swings were in the high latitudes, but tropical temperatures ranged from 22 C to 42 C. This goes against the idea that the tropics have a fixed upper limit and shows that life must have evolved to survive in those higher temperatures.

The research also shows that our current climate is actually cooler than the climate through most of the Phanerozoic. Technically, Earth is in an ice age right now, though the ice is receding and has been for thousands of years. Earth’s current GMST is 15 Celsius, lower than during most of the Phanerozoic.

But while that may sound comforting, it’s not. It’s the rate of change in the GMST that’s dangerous. Our GHG emissions are warming the planet faster than at any time during the Phanerozoic.

“Humans, and the species we share the planet with, are adapted to a cold climate,” Tierney said. “Rapidly putting us all into a warmer climate is a dangerous thing to do.”

This figure from the published research shows the climate states through the Phanerozoic. D shows the latitudinal surface air temperature gradient associated with each of the climate states. Coloured bands show the 16th to 84th percentiles, and coloured lines show the median value. Image Credit: Judd et al. 2024.

While PhanDA is generally in agreement with previous climate reconstructions, it deviates in some ways. For example, cold climate periods don’t always coincide with glaciation and ice ages. Earth’s surface is ever-changing, and that can make some conclusions difficult to reach. “Many of the traditional glacial indicators can have nonglacial origins, complicating the interpretation of the rock record, and limited outcrop of older rocks and poor age control can make it difficult to discern between isolated alpine glaciers and widespread ice sheets,” the authors explain.

But that doesn’t take much away from PhanDA. It strengthens our understanding of climate and carbon.

This figure illustrates the undeniable relationship between atmospheric carbon and a warming climate. B shows PhanDA GMST versus CO2, colour-coded by geologic era. The black dashed line shows the York regression, a statistical method used to draw a straight line between data points with some uncertainties. C shows the CO2 ranges for each of the defined climate states. Image Credit: Judd et al. 024.

Shockingly, the work suggests that Earth’s climate is even more sensitive to CO2 than some current models show.

“PhanDA GMST exhibits a strong relationship with atmospheric CO2 concentrations, demonstrating that CO2 has been the dominant force controlling global climate variations across the Phanerozoic,” the authors write in their conclusion.

NASA and the Republic of Korea’s newly created Korea AeroSpace Administration (KASA) signed a joint statement of intent Thursday affirming their interest to advance cooperation in space exploration, science, and aeronautics.

The signing took place at NASA Headquarters in Washington during the KASA’s first visit since its creation in May 2024.

“Building on years of work together both on Earth and in space, we are proud to significantly grow our partnership with the Republic of Korea and its new space agency,” said NASA Administrator Bill Nelson. “We look forward to the discoveries and innovation that our two nations will accomplish in this exciting time for space exploration.”

The countries will discuss potential cooperation in a range of areas including NASA’s Moon to Mars Architecture, space life sciences and medical operations, lunar surface science, utilization of Korea’s deep space antenna, future commercial low Earth orbit activities, and other fields of science such as heliophysics. 

The statement also acknowledges a shared commitment to the Artemis Accords, to which the Republic of Korea was an early signatory. NASA, in coordination with the U.S. Department of State and seven other founding member nations, established the Artemis Accords in 2020, reinforcing the commitment by signatory nations to the Registration Convention, the Rescue and Return Agreement, as well as best practices and norms of responsible behavior, including the public release of scientific data.

“The signing of the joint statement marks a pivotal moment in opening a new chapter for the Republic of Korea-U.S. aerospace alliance. It presents a vital opportunity for Korea to emerge as a responsible space-faring nation, and also for humanity to pursue scientific discoveries and pioneer the future,” said KASA Administrator Youngbin Yoon. “The Korea AeroSpace Administration will continue to collaborate globally for sustainable space activities and strengthen Korea’s role on the international space stage.”

In attendance at the ceremony were top officials from the Korea Aerospace Research Institute (KARI) and the Korea Astronomy and Space Science Institute (KASI). The organizations worked with NASA to share data from the Korea Pathfinder Lunar Orbiter and leverage the agency’s Deep Space Network.

The U.S. and the Republic of Korea have built and placed satellites in orbit that can track air pollution in North America and Asia and making that data and knowledge available to the world. NASA’s recently launched TEMPO (Tropospheric Emissions: Monitoring of Pollution) mission, and KARI’s GEMS (Geostationary Environment Monitoring Spectrometer), are improving life on Earth by revolutionizing the way scientists observe air quality from space, solving Earth’s greatest challenges.

Researchers found that eddies, or swirling wind patterns, increased moisture evaporation in an alfalfa field. A better understanding of the complex exchange of water and heat between the ground and atmosphere could improve remote sensing products and their use in agricultural water management.  

The station’s ECOSTRESS instrument takes high-resolution thermal infrared measurements of Earth’s surface that provide data on changes in water availability, vegetation water stress, and agricultural water use. Researchers use observations from the USGS Landsat 8 and 9 satellites and ECOSTRESS to validate climate models and update data on Earth’s surface energy (the amount of energy absorbed from the Sun and radiated back into the atmosphere).

Researchers identified various properties for flow boiling using n-perfleurohexane, a fluid used to cool electronics. A better understanding of this process can improve models for designing thermal cooling systems used in the electronics, energy, aerospace, and other industries. 

Flow boiling, a method of thermal management, uses the heat generated by a device to boil a liquid, generating vapor bubbles that lift the heat from the surface. The Flow Boiling and Condensation Experiment (FBCE) tested a flow boiling method in microgravity, where the process is less efficient; in the absence of buoyancy, bubbles grow larger and remain near the surface.

Researchers successfully manufactured a polymer of rare metals and other elements that showed high radiation resistance and has a suitable size and weight for use in space. This result provides knowledge that can support development of improved shielding for future spacecraft and extraterrestrial habitats. 

The Roscosmos investigation Shielding Composite tested the absorbed radiation dose of two polymers during 225 days on the space station using monthly monitoring by the Pille-ISS investigation. The data showed that the material has high and stable radiation shielding characteristics. Protecting crew members and equipment from radiation is an important requirement for future long-duration space missions.
