"Professor Goddard does not know the relation between action and reaction and the need to have something better than a vacuum against which to react. He seems to lack the basic knowledge ladled out daily in high schools."
--1921 New York Times editorial about Robert Goddard's revolutionary rocket work.

"Correction: It is now definitely established that a rocket can function in a vacuum. The 'Times' regrets the error."

Unlocking the Secrets of Our Galaxy's Heart Using Magnetic Fields

Universe Today - 11 hours 14 min ago

Scientists have achieved a groundbreaking milestone by creating the first detailed map of magnetic fields in one of the most chaotic regions of space, the turbulent center of our own Milky Way. Using innovative techniques to track microscopic dust grains, researchers have finally decoded the invisible forces that govern star formation in this extreme galactic environment. Their discoveries not only solve a 40 year mystery surrounding strange high speed electron streams racing through space, but also reveal how magnetic fields, stellar winds, and gas clouds perform an intricate dance that shape our Galaxy.

NASA Defines Gaps In Exoplanet Science

Universe Today - 11 hours 14 min ago

Science is driven by our desire to understand things. In some cases, where it requires significant effort and investment to develop systems that can understand new things, science benefits from a game plan that the community of researchers focused on a particular niche can rally around, even if they don’t necessarily agree on the details. In astronomy and space science, those game plans typically take the form of Decadal Surveys, produced by the National Academies to define the path forward in a specialization or sub-field. However, there are almost always follow-up reports that break down the suggestions from the Decadal Surveys into actionable plans that experts in the field then spend the next ten years executing on. One of those “tactical” plans was recently released on arXiv by the two lead scientists of NASA’s Exoplanet Exploration Program (ExEP), though it was listed as Rev H and released at least internally back in January 2025. In it, Drs. Karl Stapelfeldt and Eric Mamajek lay out 17 scientific goals that ExEP plans to work on over the next 3-5 years.

What Were the Chances of Abiogenesis?

Universe Today - 11 hours 14 min ago

Life arose early in Earth's history. Was this an inevitable process, or an extremely unlikely event that happened early on, and what does this tell us about the likelihood of life on other worlds? In a new paper, a researcher calculated the variables that went into the formation of life and found that a spontaneous emergence is theoretically feasible, but extremely unlikely. Instead, he suggests that there could be protection mechanisms or unknown self-organising principles that got life going.

Cosmic Rays Could Support Life Just Under the Ice

Universe Today - 11 hours 14 min ago

If you've ever dreamed of traveling through space as an explorer, you know there'll be some serious "downside dangers". One of them is cosmic rays. These high-speed particles slam through anything, including our bodies, damaging DNA and ripping molecules apart. As dangerous as they sound to unprotected spacefarers, they could actually help microscopic life survive hiding under the icy surfaces of places like Europa or Enceladus.

Mars Glaciers Have More Water Content than Previously Thought

Universe Today - 11 hours 14 min ago

On the slopes of Martian mountains and craters clings what appears to be flowing honey, coated in dust and frozen in time. In reality, these features are incredibly slow-moving glaciers, and their contents were once thought to be mostly rock enveloped in some ice.

Why Land Detection Is Critical for Confirming Exoplanetary Life

Universe Today - 11 hours 14 min ago

How can identifying land on exoplanets help scientists better understand whether an exoplanet could harbor life? This is what a recently submitted study hopes to address as a team of researchers investigated how identifying land on exoplanets could help dispel waterworld false positives, which occur when the data indicates an exoplanet contains deep oceans (approximately 50 Earth oceans), hence the name “waterworld”. This study has the potential to help scientists develop more efficient methods for classifying exoplanets and their compositions, specifically regarding whether they contain life as we know it, or even as we don’t know it.

What if a Baby Was Born Space?

Universe Today - 11 hours 14 min ago

If humans are planning to live off-world and colonise planets like Mars, that includes having children. But deep space and the surface of Mars aren't Earth, and there are several hazards that a gestating foetus will face, mainly microgravity and galactic cosmic rays. In a new paper, a researcher breaks down pregnancy into 10 sequential stages, evaluating what the implications of those conditions would be at each step. The author suggests that radiation would be the bigger risk.

How Satellites Are Silencing the Universe

Universe Today - 11 hours 14 min ago

Imagine if every time you turned on your phone, it accidentally jammed radio telescopes trying to detect alien signals. That's essentially what's happening as thousands of internet satellites flood Earth's orbit, creating electronic noise that's drowning out the whispers from black holes, distant galaxies, and the Big Bang itself. A massive new study reveals that our quest to connect every region of the planet is accidentally sabotaging our ability to answer the biggest questions in science and the problem is getting worse with every satellite launch.

How Space Construction Will Transform Life on Our Planet.

Universe Today - 11 hours 14 min ago

Imagine 3D printing an entire building from Moon dust, or having robots construct disaster relief shelters while humans stay safely away from danger. Imagine construction sites where materials never run out because they're literally made from the dirt beneath your feet, and where every structure is built with manufacturing level precision. What sounds like science fiction is becoming reality as engineers solve the ultimate construction puzzle, building on other planets. The innovations being pioneered for lunar bases and Martian colonies are about to transform every construction site on our home planet.

Tracking Deep Space Probes With GEO Satellites Improves Uptime

Universe Today - 11 hours 14 min ago

In astronomy, larger distances are both a blessing and a curse. They can cause issues like longer communication times, which also requires more powerful equipment, and positioning uncertainty that can affect the outcomes of measurements, especially in the outer reaches of the solar system. However, they can also be useful for a specific type of measurement called interferometry, where two systems a far distance apart can provide accurate location measurements to a third system - the same principle that GPS uses. A new paper looks at potentially using the same technique to track deep space probes rather than cars on a freeway and finds that, while it is around the same accuracy level, it is able to provide that same location data for more than double the amount of time.

AI Uncovers Subsurface Entrances on the Moon

Universe Today - 11 hours 14 min ago

How can artificial intelligence (AI) be used to locate lunar pits and skylights, which are surface depressions and openings, respectively, that serve as entrances to lava caves and lava tubes? This is what a recent study published in Icarus hopes to address as an international team of researchers investigated using machine learning algorithms to more efficiently identify pits and skylights on lunar volcanic regions (lunar maria) of the Moon. This study has the potential to help researchers develop new methods in identifying key surface features on planetary bodies that could aid in both robotic and human exploration.

Primordial Black Holes Could Act As Seeds For Quasars

Universe Today - 11 hours 14 min ago

Plenty of groups have been theorizing about Primordial Black Holes (PBHs) recently. That is in part because of their candidacy as a potential source of dark matter. But, if they existed, they also had other roles to play in the early universe. According to a recent draft paper released on arXiv by Jeremy Mould and Adam Batten of Swinburne University, one of those roles could be as the seeds that eventually form both quasars and radio galaxies.
