NASA’s Transiting Exoplanet Survey Satellite hunts for exoplanets, but its sensitive measurements of stellar brightness make it ideal for studying stellar...
Using the NASA/ESA Hubble Space Telescope and NASA’s Transiting Exoplanet Survey Satellite (TESS), astronomers have detected 8.9-hr variability in both...
Astronomers from the Giant Outer Transiting Exoplanet Mass (GOT ’EM) Survey have discovered a long-period giant planet circling the 7.4-billion-year-old...
Using the Sardinia Radio Telescope, a 64-m fully steerable radio telescope near San Basilio, Sardinia, Italy, an international team of astronomers has...
The Sombrero galaxy likely merged with a relatively massive galaxy several billions years ago. In a new study published in the Monthly Notices of the Royal...
Because of their compactness, neutron stars have an enormous gravitational pull around a billion times stronger than the Earth. This squashes every feature...
Astronomers know that stars are born in clouds of gas, but what sets off star formation, and how galaxies as a whole play into it, remains a mystery. To...
Using data from NASA’s Parker Solar Probe, a team of solar physicists calculated the distribution of electrons within the electric field of the Sun;...
Astronomers using NASA’s Transiting Exoplanet Survey Satellite (TESS) have discovered four exoplanets orbiting TOI-2076 and TOI-1807, a pair of related...
HD 265435 is a binary system with an orbital period of around 100 min that consists of a white dwarf and a hot subdwarf star.
An artist’s impression...
NASA has released a beautiful close-up shot snapped by the NASA/ESA Hubble Space Telescope of the globular cluster NGC 6380.
This Hubble image shows NGC...
An explosion of a fast-spinning strongly magnetized star, called a magneto-rotational hypernova, is the most likely explanation for the presence of unusually...
In 2011, planetary researchers using samples of the solar wind collected by NASA’s Genesis spacecraft found that solar system planetary bodies have a...
Palomar 5 is one of the sparsest star clusters in the halo of our Milky Way Galaxy and is best known for its spectacular tidal tails, spanning over 20...
In a study to be published in the Astronomical Journal, astronomers found that many exoplanet-hosting stars identified by NASA’s Transiting Exoplanet...
Terrestrial planets (Mercury, Venus, Earth, and Mars) are differentiated into three layers: a metallic core, a silicate shell (mantle and crust), and a...
The newly-discovered white dwarf, designated ZTF J190132.9+145808.7 (ZTF J1901+1458), has a mass of 1.35 solar masses and a radius of 2,140 km (1,330 miles),...
Astronomers using NASA’s Transiting Exoplanet Survey Satellite (TESS) have discovered a transiting hot-Jupiter exoplanet around a slightly evolved star...
An international team of astronomers has discovered the first convincing evidence for an electron-capture supernova, which is thought to arise from the...
Astronomers using the NASA/ESA Hubble Space Telescope have captured a striking new photo of NGC 330, an open star cluster that resides in the Small Magellanic...
