Violent flaring revealed at the heart of a black hole system
An international team of astronomers have used state-of-the-art cameras to create a high frame-rate movie of a growing black hole system at a level of detail never seen before. In the process they uncovered new clues to understanding the immediate surroundings of these enigmatic objects.

Pressure runs high at edge of solar system
Out at the boundary of our solar system, pressure runs high. This pressure, the force plasma, magnetic fields and particles like ions, cosmic rays and electrons exert on one another when they flow and collide, was recently measured by scientists in totality for the first time - and it was found to be greater than expected.

Astronomers found 20 new moons orbiting Saturn - and you can help name them
Astronomers found 20 new moons orbiting Saturn. This brings the ringed planet's total number of moons to 82, surpassing Jupiter, which has 79.

Astronomers observe year-long plateaus in decline of type Ia supernova light curves
This is a surprising finding as astronomers had expected that the light curve would not only continue decreasing but even experience a sharp drop, rather than flattening into a plateau.

Not long ago, the center of the Milky Way exploded
Researchers find evidence of a cataclysmic flare that punched so far out of the galaxy its impact was felt 200,000 light years away.

This is how a 'fuzzy' universe may have looked
Scientists simulate early galaxy formation in a universe of dark matter that is ultralight, or 'fuzzy', rather than cold or warm.

Neutrino produced in a cosmic collider far away
The neutrino event IceCube 170922A, detected with IceCube at the South Pole, appears to originate from the distant active galaxy TXS 0506+056, at a distance of 3.8 billion light years.

Record breaking observations find most remote protocluster of galaxies
An international team of astronomers has discovered a protocluster of galaxies 13.0 billion light years away. This protocluster is the most distant protocluster ever found. The discovery suggests that a large structure such as a protocluster already existed at a time when the universe was only about 800 million years old or 6 percent of its present age.

Giant exoplanet around tiny star challenges understanding of how planets form
Astronomers have discovered the first large gas giant orbiting a small star. The planet was found orbiting the nearby red dwarf star GJ 3512. This discovery challenges scientists' very understanding of how planets form: low-mass stars should have less available material to form planets.

Eyeballing a black hole's mass
There are no scales for weighing black holes. Yet astrophysicists have devised a new way for indirectly measuring the mass of a black hole, while also confirming its existence. They tested the new method on the Messier 87 active galaxy.

New hunt for dark matter: Physicists theorize a novel way to explore the nature of dark matter with lasers
A theory about what dark matter might be suggests that it could be a particle called an axion and that these could be detectable with laser-based experiments that already exist.
