Researchers from Germany and the US have discovered an exoplanet less than twice the size of Earth orbiting at about the same distance from its star, making it the closest analog to the Earth-sun system known so far.

Asteroid 2020 LD passed within the moon's distance on June 5, but wasn't discovered until June 7. It's the 45th known and the largest asteroid to sweep within a lunar-distance of Earth so far in 2020.

Astronomers at McDonald Observatory have confirmed a second planet - 7 times more massive than Earth - orbiting Proxima Centauri, the closest star to our sun.

What is the climate like on some potentially habitable exoplanets? Scientists have developed a new "decoder" to find out.

A new study of Mars' smallest moon Deimos, by scientists from the SETI Institute and Purdue University, suggests that the planet used to have rings a few billion years ago.

The theory of relativity describes black holes as being spherical, smooth and simple. Quantum theory describes them as being extremely complex and full of information. New research now proposes a surprising solution to this apparent duality.

The formation of the sun, the solar system and the subsequent emergence of life on Earth may be a consequence of a collision between our galaxy - the Milky Way - and a smaller galaxy called Sagittarius.

Cosmologists have only been able to find half the matter that should exist in the universe. With the discovery of a new astronomical phenomenon and new telescopes, these researchers say they've just found the rest.

History was made again Sunday, with the successful docking of SpaceX Crew Dragon with the International Space Station. Astronauts Bob Behnken and Doug Hurley are aboard. There are more activities to come, which you can watch online. Links here.

Researchers at the University of Geneva have confirmed the existence of an Earth-sized exoplanet orbiting in the habitable zone of Proxima Centauri, the closest star to our sun.
