On July 4, NASA’s Transiting Exoplanet Survey Satellite (TESS) finished its primary mission, imaging about 75% of the starry sky as part of a two-year-long…
Small telescope and inexpensive diffuser key to results. New detailed observations with NSF’s NOIRLab facilities reveal a young exoplanet, orbiting a young star in the…
Hubble Uses Our Moon to Probe Earth’s Atmosphere During a Lunar Eclipse Astronauts who have gazed at Earth from space have been awestruck at our…
Using the supersharp radio “vision” of the National Science Foundation’s continent-wide Very Long Baseline Array (VLBA), astronomers have discovered a Saturn-sized planet closely orbiting a…
By making their own lava and cooled glass, scientists find these materials likely aren’t responsible for the unexpected glow of some exoplanets. Arguably some of…
The rediscovery of a lost planet could pave the way for the detection of a world within the habitable ‘Goldilocks zone’ in a distant solar…
Many exoplanets known today are ‘super-Earths,’ with a radius 1.3 times that of Earth, and ‘mini-Neptunes,’ with 2.4 Earth radii. Mini-Neptunes, which are less dense,…
The newly discovered planet’s parent star is still encircled by the disk of material from which both objects formed, giving scientists a glimpse at early…
University of Warwick-led team discovers first exposed core of a planet Highly unusual planet found in the Neptunian Desert, where such massive objects are rarely…
Study estimates there may be up to 6 billion Earth-like planets in our galaxy. Earth is the only planet that’s capable of hosting life in…
Several interacting exoplanets have already been spotted by satellites. But a new breakthrough has been achieved with, for the first time, the detection directly from…
Neptune-sized planet may be remnant core of a much larger planet. The “ice giant” planets Neptune and Uranus are much less dense than rocky, terrestrial…
The newly discovered exoplanet TOI 849 b offers the unique opportunity to peer inside the interior of a planet and learn about its composition. It…
Measurements from NASA’s Transiting Exoplanet Survey Satellite (TESS) have enabled astronomers to greatly improve their understanding of the bizarre environment of KELT-9 b, one of…
An international team of researchers has found multiple planet systems orbiting red dwarf star Gliese 887. The international “RedDots” team – joined by Australian astronomers…
An exoplanet the size of Neptune has been discovered around the young star AU Microscopii, thanks in part to the work of Jonathan Gagné, a…
Astronomers have made the first measurement of spin-orbit alignment for a distant ‘super-Jupiter’ planet, demonstrating a technique that could enable breakthroughs in the quest to…
A team of researchers simulated conditions on water-rich exoplanets in the laboratory and learned something surprising about their geological composition. Out beyond our solar system,…
