Scientists are about to switch on a telescope that could photograph a black hole's event horizon

Black holes are among the most fascinating objects in the known Universe. But despite the fact that they're suspected to lurk at the centre of most galaxies, the reality is that no one has ever been able to actually photograph one.



That's because black holes, as their name implies, are very, very dark. They're so massive that they irreversibly consume everything that crosses their event horizon, including light, making them impossible to photograph....

An unexplained 'void' appears to be pushing the Milky Way through the Universe at 2 million km/h

You can’t feel it, but our planet is orbiting the Sun at speeds of roughly 100,000 km/h (62,000 mph), and something is making our Milky Way galaxy move through the Universe at more than 2 million km/h (1.2 million mph). That’s 630 km per second, and now scientists might have finally...

First Genetic Results From Scott Kelly's Year In Space Reveal DNA Mysteries

After recent events, we’re all ready to hop aboard the next flight to Mars. But before us Earthlings embark on a seven-month journey to the Red Planet, we need to understand how the harsh conditions of space can affect our bodies.


NASA is building an Solar Electric Propulsion System for Deep Space Exploration

Aerojet Rocketdyne’s operation in Redmond, Wash., has won a $67 million contract from NASA to design and develop an advanced electric propulsion system that could power future trips to an asteroid and Mars.

The goal of the 36-month project is to deliver an integrated system that could improve fuel efficiency by a factor of 10 over today’s chemical rocket...

Hundreds of hidden galaxies found behind Milky Way

Scientists have used radio telescopes to cut through the haze of the Milky Way, revealing hundreds of previously hidden galaxies lurking behind it.
These galaxies lie a mere 250 million light-years away—and they will only get closer, because they appear to be pulling us towards them at breakneck speed.

Astronomers have found evidence of ninth planet lurking in our Solar System (Not Pluto)

Nicknamed Planet Nine, it appears to be circling the Sun on a super elongated obit that takes an incredible 10,000 to 20,000 years to complete. Estimated to be about 10 times more massive than Earth and four times the size, the team says no one’s noticed it until now because of how far away it is - it’s about 149 billion km from the Sun, or 75 times more distant than Pluto.

The Case of Strange "Alien Megastructure" Just Got Weirder

Back in October, astronomers discovered a strange pattern of light near a distant star called KIC 8462852 that no one could explain. When a planet orbits a star, the star’s brightness will usually dip by just 1 percent, but KIC 8462852 has been experiencing dips of up to 22 percent, which suggests that something very, very big is zooming past.

NASA's solar-powered spacecraft Juno breaks distance record at 793 million km from the Sun

NASA's Juno mission to Jupiter has broken the record to become humanity's most distant solar-powered emissary. The milestone occurred at 11 a.m. PST (2 p.m. EST, 19:00 UTC) on Wednesday, Jan. 13, when Juno was about 493 million miles (793 million kilometers) from the sun.
