Using the ULTRACAM instrument on ESO’s 3.5-m New Technology Telescope and NASA’s Transiting Exoplanet Survey Satellite (TESS), astronomers have observed...
Astronomers using NASA’s Chandra X-ray Observatory have detected five X-ray events from G29-38, which is among the 100 closest white dwarfs. Their results...
The NASA/ESA Hubble Space Telescope has taken a picture of the Chamaeleon Cloud I, part of a large star-forming region called the Chamaeleon Cloud Complex.
This...
Astronomers have assembled a catalog of all known Galactic binaries featuring massive disks of gas and dust that are similar to the protoplanetary disks...
The temperature of a planet’s atmosphere decreases with increasing altitude, unless a shortwave absorber that causes a temperature inversion exists....
Dr. Chengcai Shen from the Harvard & Smithsonian Center for Astrophysics and colleagues have analyzed images of the so-called supra-arcade downflows...
During solar storms, the Sun expels large amounts of energetic particles that can react with the atmosphere of Earth and produce cosmogenic isotopes such...
