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.

Clumpy structure in remnant probably formed in supernova explosion itself

Application of a new statistic to x-ray images of a supernova remnant suggests that clumps were formed during the explosion.

The Milky Way kidnapped several tiny galaxies from its neighbor

Research shows our galaxy is undergoing a massive merger with its largest satellite galaxy, the Large Magellanic Cloud.

How do the strongest magnets in the universe form?

A team of astrophysicists has found a possible answer to the question of how magnetars form.

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.

Three gravitational-wave detectors sign agreement to begin joint observation

Collaboration will enable pinpointing origin of gravitational-wave events.

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.

Quantum vacuum: Less than zero energy

An international research team has investigated the extent to which negative energy is possible.

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.
