Meteorites that helped form earth may have formed in the outer solar system
Evidence suggests surface minerals of outer main-belt asteroids, proposed to have sourced building blocks of Earth's water and life, are only stable at low temperatures. These asteroids formed in distant orbits and may help explain Earth's composition.

Scientists announce discovery of supermassive binary black holes
Astronomers have discovered a supermassive black hole binary system, one of only two known such systems. The two black holes, which orbit each other, likely weigh 100 million suns each.

The new, improved Dragonfly is a galactic gas detector
The Dragonfly telescope is undergoing a metamorphosis. For the past decade, the Dragonfly Telephoto Array has conducted groundbreaking science by detecting faint starlight within dimly lit parts of the night sky. The telescope uses clusters of telephoto lenses to create images, much the way a dragonfly's eyes gather visual data. Now Dragonfly is setting its sights on extragalactic gas.

Imagining an Earthly neighbor
New modelling work provides deep insight into how an Earth-like planet orbiting the Sun-like stars closest to us, the α Centauri A/B binary, would look like, should it exist.

Black hole billiards in the centers of galaxies
Researchers provide the first plausible explanation to why one of the most massive black hole pairs observed to date by gravitational waves also seemed to merge on a non-circular orbit. Their suggested solution involves a chaotic triple drama inside a giant disk of gas around a super massive black hole in a galaxy far, far away.

Astronomers discover largest molecule yet in a planet-forming disc
Astronomers have for the first time detected dimethyl ether in a planet-forming disc. With nine atoms, this is the largest molecule identified in such a disc to date. It is also a precursor of larger organic molecules that can lead to the emergence of life.

Massive bubbles at center of Milky Way caused by supermassive black hole
In 2020, the X-ray telescope eRosita took images of two enormous bubbles extending far above and below the center of our galaxy. New research suggests the bubbles are a result of a powerful jet of activity from the supermassive black hole at the center of the Milky Way.

Powerful warm winds seen blowing from a neutron star as it rips up its companion
Using the most powerful telescopes on Earth and in space, a team of astronomers has found for the first time blasts of hot, warm and cold winds from a neutron star whilst it consumes matter from a nearby star. The discovery provides new insight into the behaviours of some of the most extreme objects in the universe.

'Closest black hole' system found to contain no black hole
Scientists report that there is no black hole in HR 6819, which is instead a 'vampire' two-star system in a rare and short-lived stage of its evolution.

Cosmic web orchestrates the progression of galaxies
The shape of galaxies and how they evolve depend on a web of cosmological filaments that run across the Universe. According to a recent study, this cosmic web plays a much bigger role than previously thought.
