Comets have long been seen as omens and portents, and it’s easy to understand why. They first appear as faint smudges of light in the sky, sometimes fading soon after and sometimes becoming brighter than the planets, with a long, glowing tail. They have been observed throughout human history, but it wasn’t until the eighteenth century that astronomers began to predict the return of some comets. Even today, we can’t predict the return of most comets until after they swing through the inner solar system. If such a comet happens to be heading toward Earth, we wouldn’t know about it until too late. But that could change thanks to our observations of meteor showers.

Comets originate from the Oort cloud, the icy remnant of our solar system’s birth that surrounds the Sun as a sphere 100,000 AU in diameter. Whether through a close collision with another Oort object or the nearby passing of a star, some of these distant chunks of ice and rock are sent tumbling toward the inner solar system. They can come from any direction in the sky, and once they dance near the Sun they may not return for hundreds or thousands of years. Any comet with a period longer than 200 years is known as a long-period comet, and these are the hardest to predict.

Most long-period comets pose no threat to Earth. They might appear bright in the evening or morning sky, but their orbits don’t cross Earth’s orbit, so there is no risk of impact. But some long-period comets could pose an impact threat to Earth. We know this in part because we’ve been hit by comets before, and in part because we observe regular meteor showers. Showers such as the Geminids, Perseids, and Orionids are caused by the dusty trails left by comets as they cross Earth’s orbit. In these cases, we have even identified the originating comets as Phaeton, Swift-Tuttle, and Halley’s. But of these, only Swift-Tuttle is a long-period comet (barely) with an orbital period of 257 years.

These connections between comets and meteor showers were made by first knowing the comet’s orbit then connecting its path to known showers. In principle, we should be able to do it the other way around. Identify what the path of a meteor shower is, and then use that to search for its long-period comet. As new telescopes such as Rubin Observatory come online, this approach could become a useful tool in the search for impact threats. A recent study on the arXiv shows how this would work.

The team ran simulations of long-period comets ranging from 200 to 4,000 years. They estimated the dust trails these hypothetical comets would produce, then set out to determine if astronomers could use these trails to work backwards to locate the originating comet while it is far from the Sun. In anticipation of having high-resolution sky surveys, the team assumed astronomers could observe them at the anticipated resolution of Rubin Observatory. They found that the orbits of many comets don’t produce showers useful for prediction, but in 17 cases, the showers could be used to identify comets months or years before they would typically be noticed.

To prove this point even further, the team also looked at a meteor shower called the ?-Hydrids, a faint shower that appears in early December. The origin of the sigma-Hydrids was not known until the appearance of Comet Nishimura in 2023. Once the orbit was determined, astronomers found a possible connection to the sigma-Hydrid showers. Using known observations of the shower before 2023, the team was able to determine a possible orbit for the comet. They found that with a Rubin-like sky search, astronomers could have found Nishimura eight months before its actual discovery.

Although no ghouls or goblins or trick-or-treaters come knocking at the International Space Station’s front hatch, crew members aboard the orbiting facility still like to get in the Halloween spirit. Whether individually or as an entire crew, they dress up in sometimes spooky, sometimes scary, but always creative costumes, often designed from materials available aboard the space station. Please enjoy the following scenes from Halloweens past even as we anticipate the costumes of the future.

In October 2021, Crew-3 NASA astronauts Raja J. Chari, Thomas H. Marshburn, Kayla S. Barron, and Matthias J.

However, bad weather at NASA’s Kennedy Space Center in Florida thwarted those super-secret spooky Halloween plans, delaying their launch until Nov. 11. Undeterred, Expedition 66 crewmembers who awaited them aboard the station held their own Halloween shenanigans. ESA astronaut Thomas G. Pesquet posted on social media that “Strange things were happening on ISS for Halloween. Aki rising from the dead (or is it from our observation window?),” referring to fellow crew member Akihiko Hoshide of the Japan Aerospace Exploration Agency.

Preparations for Next Moonwalk Simulations Underway (and Underwater) NASA’s SPHEREx observatory undergoes integration and testing at BAE Systems in Boulder, Colorado, in April 2024. The space telescope will use a technique called spectroscopy across the entire sky, capturing the universe in more than 100 colors. BAE Systems

The space telescope will detect over 100 colors from hundreds of millions of stars and galaxies. Here’s what astronomers will do with all that color.

NASA’s SPHEREx mission won’t be the first space telescope to observe hundreds of millions of stars and galaxies when it launches no later than April 2025, but it will be the first to observe them in 102 colors. Although these colors aren’t visible to the human eye because they’re in the infrared range, scientists will use them to learn about topics that range from the physics that governed the universe less than a second after its birth to the origins of water on planets like Earth.

“We are the first mission to look at the whole sky in so many colors,” said SPHEREx Principal Investigator Jamie Bock, who is based jointly at NASA’s Jet Propulsion Laboratory and Caltech, both in Southern California. “Whenever astronomers look at the sky in a new way, we can expect discoveries.”

Short for Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer, SPHEREx will collect infrared light, which has wavelengths slightly longer than what the human eye can detect. The telescope will use a technique called spectroscopy to take the light from hundreds of millions of stars and galaxies and separate it into individual colors, the way a prism transforms sunlight into a rainbow. This color breakdown can reveal various properties of an object, including its composition and its distance from Earth.

NASA’s SPHEREx mission will use spectroscopy — the splitting of light into its component wavelengths — to study the universe. Watch this video to learn more about spectroscopy. NASA’s Goddard Space Flight Center

Here are the three key science investigations SPHEREx will conduct with its colorful all-sky map.

Cosmic Origins

What human eyes perceive as colors are distinct wavelengths of light. The only difference between colors is the distance between the crests of the light wave. If a star or galaxy is moving, its light waves get stretched or compressed, changing the colors they appear to emit. (It’s the same with sound waves, which is why the pitch of an ambulance siren seems to go up as its approaches and lowers after it passes.) Astronomers can measure the degree to which light is stretched or compressed and use that to infer the distance to the object.

SPHEREx will apply this principle to map the position of hundreds of millions of galaxies in 3D. By doing so, scientists can study the physics of inflation, the event that caused the universe to expand by a trillion-trillion fold in less than a second after the big bang. This rapid expansion amplified small differences in the distribution of matter. Because these differences remain imprinted on the distribution of galaxies today, measuring how galaxies are distributed can tell scientists more about how inflation worked.

Galactic Origins

SPHEREx will also measure the collective glow created by all galaxies near and far — in other words, the total amount of light emitted by galaxies over cosmic history. Scientists have tried to estimate this total light output by observing individual galaxies and extrapolating to the trillions of galaxies in the universe. But these counts may leave out some faint or hidden light sources, such as galaxies too small or too distant for telescopes to easily detect.

With spectroscopy, SPHEREx can also show astronomers how the total light output has changed over time. For example, it may reveal that the universe’s earliest generations of galaxies produced more light than previously thought, either because they were more plentiful or bigger and brighter than current estimates suggest. Because light takes time to travel through space, we see distant objects as they were in the past. And, as light travels, the universe’s expansion stretches it, changing its wavelength and its color. Scientists can therefore use SPHEREx data to determine how far light has traveled and where in the universe’s history it was released.

Water’s Origins

SPHEREx will measure the abundance of frozen water, carbon dioxide, and other essential ingredients for life as we know it along more than 9 million unique directions across the Milky Way galaxy. This information will help scientists better understand how available these key molecules are to forming planets. Research indicates that most of the water in our galaxy is in the form of ice rather than gas, frozen to the surface of small dust grains. In dense clouds where stars form, these icy dust grains can become part of newly forming planets, with the potential to create oceans like the ones on Earth.

The mission’s colorful view will enable scientists to identify these materials, because chemical elements and molecules leave a unique signature in the colors they absorb and emit.

Big Picture

Many space telescopes, including NASA’s Hubble and James Webb, can provide high-resolution, in-depth spectroscopy of individual objects or small sections of space. Other space telescopes, like NASA’s retired Wide-field Infrared Survey Explorer (WISE), were designed to take images of the whole sky. SPHEREx combines these abilities to apply spectroscopy to the entire sky.

By combining observations from telescopes that target specific parts of the sky with SPHEREx’s big-picture view, scientists will get a more complete — and more colorful — perspective of the universe.

More About SPHEREx

SPHEREx is managed by JPL for NASA’s Astrophysics Division within the Science Mission Directorate in Washington. BAE Systems (formerly Ball Aerospace) built the telescope and the spacecraft bus. The science analysis of the SPHEREx data will be conducted by a team of scientists located at 10 institutions across the U.S. and in South Korea. Data will be processed and archived at IPAC at Caltech, which manages JPL for NASA. The mission principal investigator is based at Caltech with a joint JPL appointment. The SPHEREx dataset will be publicly available.
