The National Science Foundation says TOI-3757 b (right) is the fluffiest gas giant exoplanet to orbit a red dwarf.Illustration: NSF NOIRLabSpace has no shortage of weird and curious planets. Astronomers using the 3.5-meter telescope at Kitt Peak National Observatory report their discovery of a Jupiter-like world with roughly the same density as a marshmallow, rapidly orbiting a red dwarf star. The planet is called TOI-3757 b, and it can be found 580 light-years away from Earth in the Auriga constellation. Scientists find…

This artist’s impression shows an ultra-hot exoplanet, a planet beyond our Solar System, as it is about to transit in front of its host star. When the light from the star passes through the planet’s atmosphere, it is filtered by the chemical elements and molecules in the gaseous layer. With sensitive instruments, the signatures of those elements and molecules can be observed from Earth. Using the ESPRESSO instrument of ESO’s Very Large Telescope, astronomers have found the heaviest element yet in an exoplanet’s…

The exoplanets WASP-76 b and WASP-121 b are already known to be peculiar places, but a new discovery has raised even more questions about the composition of these celestial bodies. Astronomers studying the pair have discovered the heaviest element ever found in an exoplanet atmosphere, which is several times heavier than iron and suggests these ultra-hot Jupiter-like planets are even stranger than suspected.The two exoplanets at the center of this study are no strangers to dramatic discoveries. Both orbit their host stars…

How would Earth appear to alien astronomers? What would their observations tell them about Earth if they were searching the heavens for signs of habitability like we are? It's a fun thought experiment.But the experiment is more than just fun: It's scientifically instructive. In many ways, it's easier to study our planet and how it appears and then extrapolate those results as far as they go.A new study shows that finding evidence of life on Earth may depend on the season alien astronomers are observing.Almost nothing in…

One of the most exciting aspects of the James Webb Space Telescope (JWST) is its ability to image and gather information about exoplanets. But while JWST will give us tons of information about these celestial bodies, there’s something that it can’t do: take a high-resolution image of an earth-like exoplanet — specifically, an image where we can clearly see evidence of possible life on another world, such as land masses, clouds, and bodies of water.   Slava Turyshev of the NASA Jet Propulsion Laboratory is working on a…

The James Webb Space Telescope (JWST) has taken its first direct images of a planet orbiting a distant star. The planet, known as HIP 65426 b, is a gas giant several times more massive than Jupiter, circling its star at a distance that is about three times greater than the separation between Neptune and our sun. HIP 65426 b is only around 15 million years old—a newborn in astronomical terms—and roughly 350 light-years from Earth. You might not be impressed by the level of detail in these new planetary photographs, but…

The JWST’s size and sensitivity enabled it to collect more light from this planet than any previous observatory has obtained. (Its photo looks grainier than SPHERE’s only because the JWST observes longer, infrared wavelengths.) This allowed Hinkley, Biller and their team to refine the estimate of the planet’s mass, which they peg at about seven Jupiter masses, less than SPHERE’s estimate of about 10. Their results also help nail down the planet’s radius, which is 1.4 times that of Jupiter. Simple models of planetary…

For the first time, astronomers have used NASA's James Webb Space Telescope to take a direct image of a planet outside our solar system.The exoplanet called 'HIP 65426 b' is a gas giant, meaning it has no rocky surface and could not be habitable.The exoplanet is about six to 12 times the mass of Jupiter, and these observations could help narrow that down even further.It is young, about 15 to 20 million years old, compared to our 4.5-billion-year-old Earth."This is a transformative moment, not only for Webb but also for…
