Astronomers at MIT and elsewhere have used a massive cluster of galaxies as an X-ray magnifying glass to peer back in time, to nearly 9.4 billion years ago. In the process, they spotted a tiny dwarf galaxy in its very first, high-energy stages of star formation.

The NASA/ESA Hubble Space Telescope sees galaxies of all shapes, sizes, luminosities and orientations in the cosmos. Sometimes, the telescope gazes at a galaxy oriented sideways — as shown here. The spiral galaxy featured in this Hubble image is called NGC 3717, and it is located about 60 million light-years away in the constellation of Hydra (the Sea Serpent).

The discovery of ice deposits in craters scattered across the Moon’s south pole has helped to renew interest in exploring the lunar surface, but no one is sure exactly when or how that ice got there. A new study suggests that while a majority of those deposits are likely billions of years old, some may be more recent.

The center of our galaxy is a crowded place: A black hole weighing 4 million times as much as our Sun is surrounded by millions of stars whipping around it at breakneck speeds. This extreme environment is bathed in intense ultraviolet light and X-ray radiation. Yet much of this activity is hidden from our view, obscured by vast swaths of interstellar dust.

Titan is the only other place in the solar system with liquid oceans on its surface, but it also has huge swathes of desert covered in sand dunes. The material that makes up these dunes is commonly assumed to have fallen from the sky, but a new study suggests it may have been made on the ground instead.

Starts With a Bang!

If there’s one lesson that humanity should have learned from the 20th century, it’s this: the Universe rarely behaves the way our intuition leads us to suspect. At the start of the 1900s, we thought the Universe was governed by Newtonian gravity. We thought that the Universe was static, stationary, and infinitely old, with no beginning and no end. And we couldn’t even be sure whether the Milky Way was one of many galaxies, or whether it encompassed everything there was. Of course, developments in both theory and observation changed all of this. Newtonian gravity was superseded by General Relativity, which demonstrated that a static Universe would be unstable. Spirals (and later ellipticals) were determined to be their own “island Universes” far outside of the Milky Way, each with billions of stars of their own. And instead of an infinitely old Universe, we live in one that got its start 13.8 billion years ago during the hot Big Bang. This picture itself was revolutionary, but led to a brand new question: how did the Universe grow up?

Asteroids are chunks of rock and metal left over from the formation of the solar system, battered and shattered, orbiting the Sun all over the place, but with the vast majority of big ones between the orbits of Mars and Jupiter. Hubble Space Telescope is an Earth-orbiting observatory that looks at objects all over the Universe, which appear all over the sky. Above Earth's atmosphere it has darker skies and sharp eyesight, allowing it to peer deeply into space.

NASA and the DLR are making some progress with the Mole. The Mole has been stuck for months now, and NASA/DLR have been working to get it unstuck. After removing the mole’s housing to get a better look at it with InSight’s cameras, the team came up with a plan.
