While the NASA/ESA/CSA James Webb Space Telescope and other space telescopes previously have revealed isolated ingredients of the atmosphere of WASP-39b,...
Using images obtained by two orbiting spacecraft, NASA’s Mars Reconnaissance Orbiter and ESA’s Mars Express, planetary researchers analyzed textured...
Magnetars are neutron stars with ultra-strong magnetic fields, which can be observed in X-rays. Polarization measurements could provide information on...
The sample of material delivered to our planet from the near-Earth asteroid Ryugu contained a mixture of extraterrestrial (helium and neon) and terrestrial...
The annual ozone hole over the South Pole reached an average area of 23.2 million km2 (8.9 million square miles) between September 7 and October 13, 2022,...
The Earth’s atmosphere is always electrified to a greater or lesser extent, even in fair weather away from thunderstorms. By measuring the electrical...
Unidentified aerial phenomena (UAPs), popularly known as UFOs, are of interest for both national security and air safety and NASA’s independent study...
Gliese 1252b, a super-Earth exoplanet that orbits an M-dwarf star 67 light-years away, retains only a tenuous mineral exosphere.

Barium, a chemical element with the symbol Ba and atomic number 56, is the heaviest element detected to date in any exoplanetary atmosphere.
This artist’s...
Methylated gases are made when organisms add a carbon and three hydrogen atoms to an undesirable chemical element. Called methylation, this process can...
Both the first and second interstellar meteors, IM1 and IM2, are outliers in material strength and may have originated in supernova explosions, according...
ZTF J1813+4251 is a 51-minute-orbital-period, fully eclipsing binary system consisting of a star with a temperature comparable to that of the Sun but...
Nitrous oxide (also known as laughing gas) — a product of microbial nitrogen metabolism — is a compelling exoplanet biosignature gas with distinctive...
A light pillar is an optical phenomenon where a column of light can be seen emanating from a light source. If the light comes from the Sun, the phenomenon...
The high-temperature planetary-scale-sized structure is at least 130,000 km (80,778 miles) long, according to a new study led by JAXA scientists.
A panning-view...
Intensity data of visible light seen by a camera can be plotted as a 3D elevation landscape. The new computer animation, created by citizen scientist and...
Using the Near-Infrared Camera (NIRCam) and the Near-Infrared Spectrograph (NIRSpec) aboard the NASA/ESA/CSA James Webb Space Telescope, astronomers have...
Exoplanets smaller than Neptune are common around red dwarf (M-dwarf) stars, and many of those that transit their host stars constitute the bulk of known...
Using the spectral data from the NASA/ESA/CSA James Webb Space Telescope, astronomers have found evidence for silicate clouds as well as water, methane,...
Even though Mars does not have a global magnetic field like the Earth, it still possesses multiple kinds of aurora. One of these is proton aurora, which...
