Today's Top Space Headline --"Could an Alien Civilization Hack Planet Earth?"

With all the news stories these days about computer hacking, it probably comes as no surprise that someone is worried about hackers from outer space. Yes, there are now scientists who fret that space aliens might send messages that worm...        

Go for GOLD, SES-14!

While we can measure properties of these upper layers using ground-based instruments, satellite-borne remote sensing instruments can give us a more frequent, global, and often higher spatial resolution perspective. And that is precisely what NASA’s Global-scale Observations of the Limb and Disk (GOLD) mission will deliver.

SpaceX launches Spanish satellite from California

A SpaceX rocket carrying a Spanish satellite has blasted off from Vandenberg Air Force Base in California.

New NASA Map Shows Antarctica Rapidly Melting --"Suggests That We’re on Thin Ice"

If the world was a glass of water, Antarctica would be the biggest ice cube floating in it. The southernmost continent is almost completely covered by a thick layer of ice known as the Antarctic ice sheet, which makes up...        

"Will It Defy Einstein's Theory & Laws of Physics?" --Strange Mystery Star Orbiting Milky Way's Supermassive Black Hole

"We have been waiting 16 years for this," said Devin Chu with UCLA's Galactic Center Group. "We are anxious to see how the star will behave under the black hole's violent pull. Will S0-2 follow Einstein's theory or will the...      ...

Rare first moment of stellar explosion captured by amateur astronomer

(Kavli Institute for the Physics and Mathematics of the Universe) An amateur astronomer testing his new camera captures the moment a supernova became visible in the night sky, which has helped an international team of researchers to test their theory about the beginning stages of a stellar explosion.

Astronomers discover S0-2 star is single and ready for big Einstein test

(W. M. Keck Observatory) A team of astronomers led by Devin Chu, a UCLA scientist from Hawaii, has found that S0-2 does not have a significant other after all, or at least one that is massive enough to get in the way of critical measurements that astronomers need to test Einstein's Theory of General Relativity.

Goonhilly goes deep space

Until now, if you’re an entrepreneur planning future missions beyond Earth, you’d have to ask a big space agency to borrow their deep-space antennas. Now, thanks to the UK’s county of Cornwall and ESA, you’ll have a commercial option, too.

Astronomers discover S0-2 star is single and ready for big Einstein test

Astronomers have the "all-clear" for an exciting test of Einstein's Theory of General Relativity, thanks to a new discovery about S0-2's star status.

Swarm trio becomes a quartet

With the aim of making the best possible use of existing satellites, ESA and Canada have made a deal that turns Swarm into a four-satellite mission to shed even more light on space weather and features such as the aurora borealis.

Novel search strategy advances the hunt for primordial black holes

Some theories of the early universe predict density fluctuations that would have created small "primordial black holes," some of which could be drifting through our galactic neighborhood today and might even be bright sources of gamma rays.

Surfing complete

Slowed by skimming through the very top of the upper atmosphere, ESA's ExoMars has lowered itself into a planet-hugging orbit and is about ready to begin sniffing the Red Planet for methane.

Image: Hypervelocity impact testing

What looks like a mushroom cloud turned sideways is actually the instant an 2.8 mm-diameter aluminium bullet moving at 7 km/s pierces a spacecraft shield, captured by a high-speed camera.

Curiosity update, sols 1927-1971: Ready to resume drilling

After a hiatus of nearly 500 sols, Curiosity is ready to attempt drilling into a Mars rock again.

Amateur astronomer captures rare first light of massive exploding star

(W. M. Keck Observatory) An amateur astronomer in Argentina captured images of a distant galaxy before and after the supernova's 'shock breakout' - when a supersonic pressure wave from the exploding core of the star hits and heats gas at the star's surface to a very high temperature, causing it to emit light and rapidly brighten.

Trilobites: He Took a Picture of a Supernova While Setting Up His New Camera

Astronomers rarely see the beginnings of these explosions, but an Argentine amateur’s lucky picture helped them study the start of a massive star’s violent death.

Amateur astronomer captures rare first light from massive exploding star

(University of California - Berkeley) First light from a supernova is hard to capture; no one can predict where and when a star will explode. An Argentinian amateur astronomer has now captured on film this first light, emitted when the exploding core hits the star's outer layers: shock breakout. Show More Summary

From the Farside --Third Reich's Weird Cosmology: "Why Hitler Thought the Universe Formed from Ice"

Nazis came to believe a lot of strange and horrific ideas as they built up their Third Reich and attacked the world. One of the weirdest was the theory about the creation of the universe that Hitler and other top...
