According to new research, most extrasolar planets do not get enough radiation to support photosynthesis, which places limits on how many might be habitable. The post Most Exoplanets won’t Receive Enough Radiation to S...

NASA is still investigating the computer glitch that has left the Hubble Space Telescope offline after an unsuccessful attempt to turn on its backup computer for the first time in space.

Much more liquid water may lie beneath Mars' south pole than scientists had thought -- or there may be something going on down there that they don't fully understand.

While exploring two exoplanets in a bright nearby star system, ESA's exoplanet-hunting Cheops satellite has unexpectedly spotted the system's third known planet crossing the face of the star. This transit reveals excitin...

Some exoplanet searches could be missing nearly half of the Earth-sized planets around other stars. New findings from a team using the international Gemini Observatory and the WIYN 3.5-meter Telescope at Kitt Peak Nation...

The release of the U.S. government's highly anticipated UFO report has whipped up a blend of reactions, from UFO groups to individuals in military, academic and scientific circles.

The International Space Station was photographed crossing the disk of the sun just as astronauts Thomas Pesquet and Shane Kimbrough worked outside to install the second Roll-Out Solar Array.

A study measuring water concentration in Venus's atmosphere concluded Monday that life as we know it is not possible among the sulphuric acid droplets that make up the planet's famously cloudy skies.

NOIRLab Press Releases:

Life in the clouds of Venus is impossible due to the extremely low amount of water despite last year's findings suggesting the presence of organic material.

Astronomers are on the search for a mysterious signal that could map the early universe.

Astronomers may have finally discovered convincing evidence of an elusive kind of supernova, called the electron-capture supernova, that may explain the Crab Nebula.

A worldwide team led by UC Santa Barbara scientists at Las Cumbres Observatory has discovered the first convincing evidence for a new type of stellar explosion--an electron-capture supernova. While they have been theoriz...
