A gas giant exoplanet 634 light-years away has a quirk in its atmosphere that suggests it may have swallowed a smaller world.
Scientists detected a high-energy neutrino emission from within the Milky Way for the very first time using the IceCube Neutrino Observatory. Neutrinos are incredibly hard to detect.
For the first time, starlight has been detected in galaxies burning brightly with the fury of feeding black holes in the first billion years of the Universe.
Astronomers have made a discovery that confirms the existence of gravitational waves, which sound like the hum at a large gathering. These ripples in space-time were proposed by Albert Einstein over a century ago.
In 2020 astronomers found six objects orbiting Sagittarius A* that are unlike anything in the galaxy. They are so peculiar that they have been assigned a brand-new class – what astronomers are calling G objects.
A team of international scientists has used NASA’s James Webb Space Telescope to detect a new carbon compound in space for the first time. It was detected in a young star system known as d203-506, which is located in the Orion Nebula.
New results from the James Webb Space Telescope find that radiation from ordinary galaxies cleared the primordial haze left over from the Big Bang, allowing the first light to shine through the early universe.
Astronomers have just found a second example of a white dwarf acting as a pulsar, following the first discovery in 2016.
Using the Green Bank Telescope (GBT), US astronomers have detected a new binary millisecond pulsar. The newly found pulsar, designated PSR J0212+5321, belongs to the "redback" subclass and is located relatively nearby.
An object orbiting a star 1,400 light-years away is seriously confronting our notions of what's possible in the Universe.
In a recent paper a UK physicist uses past missions and recent findings to encourage the importance of searching for life in the atmosphere of the solar system's most inhospitable planet, Venus.
Phosphorus is the least abundant essential element necessary for life, and its recent detection in icy grains from Enceladus could redefine how we look at life beyond Earth.
A group of Australian space scientists discovered a white dwarf star that appears to be in the beginning stages of crystallizing into a celestial diamond.
When scientists detected the gamma-ray burst known as GRB 221009A on Oct. 9, 2022, they dubbed it the brightest of all time, or BOAT. Follow-up studies showed that GRB 221009A was 70 times brighter and far more energetic than the previous record holder.
An international team of astronomers has detected complex organic molecules in the most distant galaxy to date using NASA’s James Webb Space Telescope.
