SunStroke! Landscape of Comet Dramatically Altered As It Approached the Sun  

The Rosetta spacecraft documented unique changes spotted on comet 67p/Churyumov-Gerasimenko as it approached the sun --growing fractures, collapsing cliffs and rolling boulders on the comet's surface. A study published March 21, 2017 in the journal Science summarizes the types of surface changes observed during the two years that the European Space Agency's Rosetta spacecraft spent investigating comet 67P/Churyumov-Gerasimenko. Notable differences are seen before and after the comet'

The Missing Galaxies of the Cosmos  

Astronomers have developed a way to detect the ultraviolet (UV) background of the Universe, which could help explain why there are so few small galaxies in the cosmos. UV radiation is invisible but shows up as visible red light when it interacts with gas. An international team of researchers has now found a way to measure it using instruments on Earth. The researchers said their method can be used to measure the evolution of the UV background through cosmic time, mapping how and when it

New Chilean Atacama Desert Observatory --To Probe First Signals of the Big Bang  

The silence of an immense desolate land in which to search for reverberations coming from the time at which everything began. The Simons Observatory will be built in the Chilean Atacama desert at an altitude of several thousand meters for the purposes of studying primordial gravitational waves which originated in the first instants of the Big Bang.

NASA: "Giant Mars Volcano and Earth's Dinosaurs Went Extinct About the Same Time"  

  "We estimate that the peak activity for the volcanic field at the summit of Arsia Mons probably occurred approximately 150 million years ago--the late Jurassic period on Earth--and then died out around the same time as Earth's dinosaurs," said Jacob Richardson, a postdoctoral researcher at NASA's Goddard Space Flight Center in Greenbelt, Maryland. "It's possible, though, that the last volcanic vent or two might have been active in the past 50 million years, which is very recent in g

Law Controlling Bizarre Behavior of Black Holes --"Points to a Deeper Understanding of Realty"  

A team of scientists has discovered that a law controlling the bizarre behavior of black holes out in space—is also true for cold helium atoms that can be studied in laboratories. "It's called an entanglement area law," says Adrian Del Maestro, a physicist at the University of Vermont who co-led the research. That this law appears at both the vast scale of outer space and at the tiny scale of atoms, "is weird," Del Maestro says, "and it points to a deeper understanding of reality." Th...

Mars, The Ringed Planet? --"Had Them in the Distant Past and May Again With the Disintegration of Its Mystery Moon, Phobos"

That's the theory put forth by Purdue University scientists have developed a model that suggests that debris that was pushed into space from an asteroid or other body slamming into Mars around 4.3 billion years ago and alternates between becoming a planetary ring and clumping up to form a moon. A theory exists that Mars' large North Polar Basin or Borealis Basin, which covers about 40 percent of

ESO --"Dark Matter Halos of Early Galaxies Much Larger and Diffuse" --Dominated By Normal Matter (VIDEO)  

New observations indicate that massive, star-forming galaxies during the peak epoch of galaxy formation, 10 billion years ago, were dominated by baryonic or 'normal' matter. This is in stark contrast to present-day galaxies, where the effects of mysterious dark matter seem to be much greater. This surprising result was obtained using ESO's Very Large Telescope and suggests that dark matter was less influential in the early universe than it is today. Schematic representation of rotati

This 10 million light year-wide ring made up of small galaxies is expanding rapidly like a mini Big Bang.

Stellar Nursery Roars to Life --"An Intense, Dramatic Growth Spurt"  

A massive protostar, deeply nestled in its dust-filled stellar nursery, recently roared to life, shining nearly 100 times brighter than before. This outburst, apparently triggered by an avalanche of star-forming gas crashing onto the surface of the star, supports the theory that young stars can undergo intense growth spurts that reshape their surroundings.

  Pluto has long been viewed as a distant, cold and mostly dead world, but the first spacecraft to pass by it last year revealed many surprises about this distant dwarf planet. The data from the New Horizons flyby finished downloading to Earth in October, and while it will take many years for scientists to complete their inventory and model the results, early studies offer intriguing hints of its complex chemistry, perhaps even some form of pre-biological processes below Pluto's sur...

The signal is similar to one seen by Fermi at the center of our own Milky Way galaxy. Surprisingly, the latest Fermi data shows the gamma rays in Andromeda -- also known as M31 -- are confined to the galaxy's center instead of spread throughout. To explain this unusu
