Most Distant and Youngest Supermassive Black Hole Discovered to Date

This artist’s concept shows the most distant supermassive black hole ever discovered. It is part of a quasar from just 690 million years after the Big Bang. / Robin Dienel/Carnegie Institution for Science 12.06.2017 Scientists have uncovered a rare relic from the early universe: the farthest known supermassive black hole. This matter-eating beast is 800 million[…]

Black Holes are Simpler than Forests and Science has Its Limits

Complex nature. Photo by Alan L/Flickr By Dr. Martin Rees / 12.01.2017 Emeritus Professor of Cosmology and Astrophysics University of Cambridge Albert Einstein said that the ‘most incomprehensible thing about the Universe is that it is comprehensible’. He was right to be astonished. Human brains evolved to be adaptable, but our underlying neural architecture has barely changed since[…]

Solar System’s First Observed Interstellar Visitor Dazzles Scientists

Artist’s concept of interstellar asteroid 1I/2017 U1 (‘Oumuamua) as it passed through the solar system after its discovery in October 2017. The aspect ratio of up to 10:1 is unlike that of any object seen in our own solar system. Credits: European Southern Observatory/M. Kornmesser 11.20.2017 Astronomers recently scrambled to observe an intriguing asteroid that zipped[…]

First Detection of Gravitational Waves and Light Produced by Colliding Neutron Stars

In a galaxy far away, two dead stars begin a final spiral into a massive collision. The resulting explosion unleashes a huge burst of energy, sending ripples across the very fabric of space. In the nuclear cauldron of the collision, atoms are ripped apart to form entirely new elements and scattered outward across the Universe.[…]

Mars Rover Opportunity on Walkabout Near Rim

The Pancam on NASA’s Mars Exploration Rover Opportunity took the component images of this enhanced-color scene during the mission’s “walkabout” survey of an area just above the top of “Perseverance Valley,” in preparation for driving down the valley. NASA/JPL-Caltech/Cornell/Arizona State Univ. 06.23.2017 NASA’s senior Mars rover, Opportunity, is examining rocks at the edge of Endeavour Crater[…]

Astronomers Find Planet Hotter Than Most Stars

This artist’s concept shows planet KELT-9b orbiting its host star, KELT-9. It is the hottest gas giant planet discovered so far. / NASA, JPL-Caltech A newly discovered Jupiter-like world is so hot, it’s being vaporized by its own star. With a dayside temperature of more than 7,800 degrees Fahrenheit (4,600 Kelvin), KELT-9b is a planet[…]

LIGO Detects More Gravitational Waves, from Even More Ancient and Distant Black Hole Collisions

Artist’s conception of two merging black holes, spinning in a nonaligned fashion. LIGO/Caltech/MIT/Sonoma State (Aurore Simonnet) By Dr. Sean McWilliams / 06.01.2017 Assistant Professor of Physics and Astronomy West Virginia State University For the third time in a year and a half, the Advanced Laser Interferometer Gravitational Wave Observatory has detected gravitational waves. Hypothesized by[…]

Cassini Finds Saturn Moon May Have Tipped Over

Working with image data from NASA’s Cassini mission, researchers have found evidence that Saturn’s moon Enceladus may have tipped over, reorienting itself so that terrain closer to its original equator was relocated to the poles. This phenomenon is known as true polar wander. / NASA/JPL-Caltech/Space Science Institute/Cornell University 05.30.2017 Saturn’s icy, ocean-bearing moon Enceladus may have[…]

Hubble Catches Black Hole Born from Collapsing Star

A team of astronomers at The Ohio State University watched a star disappear and possibly become a black hole. Instead of becoming a black hole through the expected process of a supernova, the black hole candidate formed through a “failed supernova.” / Credits: NASA’s Goddard Space Flight Center/Katrina Jackson “Massive fails” like this one in a[…]
