Published on Monday, Nov. 27, in The Astrophysical Journal Supplement, the catalog serves as a collaborative effort involving 170 scientists globally.
Life on Mercury?
Salt glaciers uncovered on Mercury, the second planet from the sun, could have implications for the habitability of this tiny planet and similar worlds beyond the solar system.
New research pokes holes in the idea that the cosmos expanded and then contracted before beginning again.
Researchers simulated what would happen if a rogue star were to come within 100 astronomical units of the Sun.

Astronomers have found a massive planet orbiting a small, cool star, and planet formation theories struggle to explain its existence.
Save this for later! From the Moon to the planets to the stars, read about the celestial events happening in December 2023!
Labroots recently shared key celestial events for November 2023 which offered skywatchers an opportunity to witness 16 days of events that included numerous meteor showers, comets, and planetary encounters. Now, Labroots wishes to share with you 22 days of celestial events for December 2023 that will ensure astronomy fans will not be disappointed. Each event is labeled in all caps for the type of event (e.g., MOON, PLANET, COMET, etc.) to provide skywatchers additional excitement to catch these incredible events!
December 1 (MOON and STAR): The Earth’s Moon will pass between 1–2 degrees from the star Pollux, which is located just under 34 light-years from Earth and resides within the constellation Gemini.
Researchers are perplexed by the discovery of an exoplanet with a mass that greatly surpasses what would be predicted given its closeness to the parent star.

A recent study published in Nature discusses the confirmation of an exoplanetary system based on data collected in 2020. The system, known as HD 110,067, possesses six planets whose orbits are in resonance with each other, or “in sync”, meaning which could offer profound insights into the formation and evolution of planetary systems throughout the cosmos. All the planets exhibit sizes between Earth and Neptune, also known as sub-Neptunes, and was conducted by an international team of researchers using data from NASA’s Transiting Exoplanet Survey Satellite (TESS) and the European Space Agency’s CHaracterising ExOPlanet Satellite (Cheops).

“This discovery is going to become a benchmark system to study how sub-Neptunes, the most common type of planets outside of the solar system, form, evolve, what are they made of, and if they possess the right conditions to support the existence of liquid water in their surfaces,” said Dr. Rafael Luque, who is a Postdoctoral Scholar in the Department of Astronomy and Astrophysics at the University of Chicago and lead author of the study.
