A fragment of a planet that has survived the death of its star has been discovered by University of Warwick astronomers in a disc of debris formed from destroyed planets, which the star ultimately consumes.
Cutting-edge VLTI instrument reveals details of a storm-wracked exoplanet using optical interferometry
It is known that gas giants around other stars are often located very near their sun. According to accepted theory, these gas planets were formed far away and subsequently migrated to an orbit closer to the star.
Study co-authored by UCLA astronomer provides close look at what might be happening in other, more energetic galaxies
Advanced infrared and microwave sounding systems, usually onboard traditional polar-orbiting satellites, provide atmospheric sounding information critical for nowcasting and weather forecasting through data assimilation in numerical weather prediction models. This means weather forecasts have become...
Researchers have detected a radio signal from abundant interstellar dust in MACS0416_Y1, a galaxy 13.2 billion light-years away in the constellation Eridanus. Standard models can't explain this much dust in a galaxy this young, forcing us to rethink the history of star formation. Researchers now thi...
Astronomers found a pulsar hurtling through space at nearly 2.5 million miles an hour -- so fast it could travel the distance between Earth and the Moon in just 6 minutes. The discovery was made using NASA's Fermi Gamma-ray Space Telescope and the National Science Foundation's Karl G. Jansky Very La...
For some distant worlds, carbon monoxide may actually be compatible with a robust microbial biosphere
The stress of spaceflight gives viruses a holiday from immune surveillance, putting future deep-space missions in jeopardy
ABERDEEN PROVING GROUND, Md. (March 13, 2019) -- NASA officials say that some rare and distinct meteorites found on Earth were actually blasted off Mars by a large impact event. One such rock from the red planet made its way to an Army laboratory recently for a special X-ray look inside.
ExoMars is a space mission of the European Space Agency (ESA) in cooperation with the Russian space agency Roskosmos. ExoMars stands for exobiology on Mars: for the first time since the 1970s, active research is being conducted into life on Mars.
In late 2018, the Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) spacecraft arrived at Bennu, the asteroid it will be studying and sampling over the next several years.
