A new investigation by an international team of astronomers using data from the NASA/ESA/CSA James Webb Space Telescope into K2-18 b, an exoplanet 8.6 times as massive as Earth, has revealed the presence of carbon-bearing molecules including methane and carbon dioxide. The discovery adds to recent studies suggesting that K2-18 b...
Astronomers have discovered the first "bubble of galaxies," an almost unimaginably huge cosmic structure thought to be a fossilized remnant from just after the Big Bang sitting in our galactic backyard.
A pair of astrophysicists, one with Kindai University, the other the National Astronomical Observatory of Japan, both in Japan, have found possible evidence of an Earth-like planet residing in the Kuiper Belt. In their paper published in The Astronomical Journal, Patryk Sofia Lykawka and Takashi Ito describe properties of the...
New Giant Planet Is Evidence of Possible Planetary Collisions A Neptune-sized planet denser than steel has been discovered by an international team of astronomers, who believe its composition could be the result of a giant planetary clash. TOI-1853b's mass is almost twice that of any other similar
Researchers from the University of Arizona have found a youthful exoplanet that may shed light on this phenomenon and offer insights into how planets form. Illustrations of the Milky Way exhibit a spiraling design of "arms" loaded with stars that radiate from the center. Comparable formations are s
On October 14, 2023, the Americas will experience a partial solar eclipse, but from only eight U.S. states will it be possible to see the 'ring of fire' annular solar eclipse.
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered a new giant exoplanet transiting a nearby M-dwarf star. The newfound alien world, designated TOI-4860 b, is comparable in size and mass to Saturn. The finding is reported in a paper published August 2 on the pre-print...
Extraordinarily high-energy gamma rays have been found emanating from the sun, and none of our theoretical models can explain why there are so many of them
New research conducted by scientists from NASA and Japan’s Osaka University suggests that rogue planets, or worlds that drift through space untethered to a star, significantly outnumber planets that orbit stars. The results indicate that NASA’s Nancy Grace Roman Space Telescope, scheduled for launch
