Hubble captures gravity-lensed quasar

Clustered at the center of this image are six luminous spots of light, four of them forming a circle around a central pair. Appearances can be deceiving, however, as this formation is not composed of six individual galaxies, ...

What Earth's gravity reveals about climate change

On March 17, 2002, the German-U.S. satellite duo GRACE (Gravity Recovery and Climate Experiment) was launched to map the global gravitational field with unprecedented precision. The mission lasted 15 years, more than three ...

Suspects in the quenching of star formation exonerated

Supermassive black holes millions to billions times the mass of our Sun lie at the heart of most, maybe all large galaxies. Some of these power brilliantly luminous, rapidly growing objects called active galactic nuclei that ...

Juno probe discovers surprising activity in Jupiter's interior

NASA's Juno spacecraft has plumbed the depths of Jupiter, revealing that the planet's famous bands of swirling winds extend thousands of kilometres down. The work is the sharpest glimpse yet into Jupiter's interior.

A new spin on Saturn's peculiar rotation

Tracking the rotation speed of solid planets, like the Earth and Mars, is a relatively simple task: Just measure the time it takes for a surface feature to roll into view again. But giant gas planets Jupiter and Saturn are ...

Black Holes in Star Clusters stir up Time and Space (w/ Video)

(PhysOrg.com) -- Within a decade scientists could be able to detect the merger of tens of pairs of black holes every year, according to a team of astronomers at the University of Bonn’s Argelander-Institut fuer Astronomie, ...

Studying how black holes grow

Black holes are some of the most exotic objects in the universe. They are the final evolutionary stage of giant stars much larger than the sun. When these stars explode, their cores collapse down to the size of large asteroid. ...
