The cosmic mass monsters clear the way for the formation of new suns in satellite galaxies.

Read moreAstronomers observed the star decreasing in brightness by a factor of 30, so that it nearly disappeared from the sky. While many stars change in brightness because they pulsate or are eclipsed by another star in a binary system, it's exceptionally rare for a star to become fainter over a period of several months and then brighten again.

Read moreResearchers discovered a titanic galactic wind driven by a supermassive black hole 13.1 billion years ago. This is the earliest-yet-observed example of such a wind to date and is a telltale sign that huge black holes have a profound effect on the growth of galaxies from the very early history of the Universe.

Read moreFour planets locked in a perfect rhythm around a nearby star are destined to be pinballed around their solar system when their sun eventually dies.

Read moreThe moons of planets that have no parent star can possess an atmosphere and retain liquid water. Astrophysicists have calculated that such systems could harbor sufficient water to make life possible - and sustain it.

Read moreEven though these objects are thousands of millions of times smaller than their host galaxies our current view is that the Universe can be understood only if the evolution of galaxies is regulated by the activity of these black holes, because without them the observed properties of the galaxies cannot be explained.

Read moreAn international group of collaborators have discovered a new, temperate sub-Neptune sized exoplanet with a 24-day orbital period orbiting a nearby M dwarf star. The recent discovery offers exciting research opportunities thanks to the planet's substantial atmosphere, small star, and how fast the system is moving away from the Earth.

Read moreA research group has revealed more about the lifespan of supermassive black holes. They accidentally caught a bright phase AGN signal from the Arp 187 galaxy with no signal from the nucleus.

Read moreThis is the earliest epoch in the universe for which there is a measurement of the atomic hydrogen content of galaxies. The new result is a crucial confirmation of the group's earlier result, where they had measured the atomic hydrogen content of galaxies 8 billion years ago, and pushes our understanding of galaxies to even earlier in the universe.

Read moreAn investigation questions one of the most interesting findings about the dynamics of the Milky Way in recent years: the precession, or the wobble in the axis of rotation of the disc warp is incorrect.

Read moreThe first detailed cross-section of a galaxy broadly similar to the Milky Way reveals that our galaxy evolved gradually, instead of being the result of a violent mash-up. The finding throws the origin story of our home into doubt.
