There may be far more water on the Moon than previously thought, according to two studies published Monday raising the tantalising prospect that astronauts on future space missions could find refreshment -- and maybe even fuel -- on the lunar surface.

The atmosphere of Venus contains a gas that on Earth can be attributed to living organisms, scientists said Monday, a discovery the head of NASA called "the most significant development yet" in the hunt for extraterrestrial life.

The sudden dimming of one of the Milky Way's brightest stars, Betelgeuse, could be due to a dust cloud spewing up from its surface, astronomers said on Thursday.

The question of whether ancient life could have existed on Mars centres on the water that once flowed there, but new research published Monday suggests that many of the Red Planet's valleys were gouged by icy glaciers not rivers.

Astrophysicists have proposed a novel method designed to find black holes in the outer reaches of the Solar System as well as to track down whether the hypothesized Planet Nine really exists.

How old is Mars? Certainly older than previous estimates according to scientists who have conducted simulations of the impacts that produced the mixed Mars mantle during the early years of the formation of our Solar System.

Astronomers have noted that the star Betelgeuse is becoming less bright, appearing especially faint in the night sky. The dimming represents the biggest dip in brightness of a star yet recorded. Is this the beginning of the end?

The detection of a distant galaxy, far more massive than the Milky Way reveals that the 'cores' of massive galaxies had already formed 1.5 billion years after the Big Bang, this is some 1 billion years earlier than calculations suggested.

Bridging Cities of Galaxies: Planck has discovered a bridge of hot gas that connects galaxy clusters Abell 399 (lower center) & Abell 401 (top left). The galaxy pair is located about a billion light-years from Earth. The gas bridge extends approximately 10 million light-years between them. The image shows the 2 galaxy clusters as seen at optical wavelengths with ground-based telescopes & through the Sunyaev-Zel'dovich effect (in orange) with the Planck satellite.

The Hubble Space Telescope has revisited the famous Pillars of Creation, revealing a sharper and wider view of the structures in this visible-light image. Astronomers combined several Hubble exposures to assemble the wider view. The towering pillars are about 5 light-years tall. The dark, finger-like feature at bottom right may be a smaller version of the giant pillars. The pillars are bathed in the blistering ultraviolet light from a grouping of young, massive stars located off the top of the i NASA/ESA

This artist’s impression shows exocomets orbiting the star Beta Pictoris. Astronomers analysing observations of nearly 500 individual comets made with the HARPS instrument at ESO’s La Silla Observatory have discovered two families of exocomets around this nearby young star. The first consists of old exocomets that have made multiple passages near the star. The second family, shown in this illustration, consists of younger exocomets on the same orbit, which probably came from the recent break ESO/L. Calçada
