Saturn’s Bizarre ‘UFO Moons’ –“Fragments of Large Moons that Disintegrated Billions of Years Ago”
19th April 2017 | dailygalaxy.com | Space

Strange flying-saucer-shaped moons embedded in Saturn’s rings have baffled scientists studying images transmitted by the Cassini Spacecraft. Past research suggests that the oddly shaped moons, Pan and Atlas, are born largely from clumps of icy particles in the rings themselves, a discovery that could shed light on how Earth and other planets formed from the disk of matter that once surrounded our newborn sun.

NASA Scientists Find Dynamo at Lunar Core May Have Formed Magnetic Field
19th April 2017 | nasa.gov | Space

The moon no longer has a magnetic field, but NASA scientists are publishing new research that shows heat from crystallization of the lunar core may have driven its now-defunct magnetic field some 3 billion years ago.

When the Sun Turns Off the Lights
19th April 2017 discovermagazine.com | Space

The sun’s power isn’t limited to lighting and heating our home planet — it could create chaos by way of its coronal mass ejections (CME). These intense releases of magnetic energy can, on rare occasions, cause geomagnetic disturbances on Earth.

Black holes theorized in the 18th century
18th April 2017 phys.org | Ancient, Space

Black holes are not made up of matter, although they have a large mass. This explains why it has not yet been possible to observe them directly, but only via the effect of their gravity on the surroundings. They distort space and time and have a really irresistible attraction. It is hard to believe that the idea behind such exotic objects is already more than 230 years old.

What Does a Black Hole Really Look Like?

39-year-old drawing hints at what the Event Horizon Telescope may have just captured: the true shape of a black hole

The Mystery of How Black Holes Collide and Merge Is Beginning to Unravel
18th April 2017 | seeker.com | Space

Last year, scientists announced that they had finally observed gravitational waves, the elusive and long sought-after ripples in the fabric of spacetime that were first posited by Albert Einstein. The waves came from a catastrophic event — the collision of two black holes located about 1.3 billion light years away from Earth — and the released energy undulated across the universe, much like ripples in a pond.

First ‘image’ of a dark matter web that connects galaxies

Researchers have been able to capture the first composite image of a dark matter bridge that connects galaxies together.

Muons Bring New Physics within Reach
17th April 2017 | scientificamerican.com | Space, Tech

In the search for new physics, experiments based on high-energy collisions inside massive atom smashers are coming up empty-handed. So physicists are putting their faith in more-precise methods: less crash-and-grab and more watching-ways-of-wobbling.

Sun’s UV Light Helped Spark Life
17th April 2017 | space.com | Space

High energy, ultraviolet radiation from the sun is a known to hazard to life, yet the energy provided by our star has played an important role as the essential driver of life on Earth.

Earth-sized ‘Tatooine’ planets could be habitable
17th April 2017 phys.org | Space

With two suns in its sky, Luke Skywalker’s home planet Tatooine in “Star Wars” looks like a parched, sandy desert world. In real life, thanks to observatories such as NASA’s Kepler space telescope, we know that two-star systems can indeed support planets, although planets discovered so far around double-star systems are large and gaseous. Scientists wondered: If an Earth-size planet were orbiting two suns, could it support life?

Second ‘Great Spot’ found at Jupiter, cold and high up
17th April 2017 | yahoo.com | Space

Another “Great Spot” has been found at Jupiter, this one cold and high up.

Scientists reported Tuesday that the dark expanse is 15,000 miles (24,000 kilometers) across and 7,500 miles (12,000 kilometers) wide.

Cassini finds final ingredient for alien life in Enceladus’s sea
16th April 2017 | newscientist.com | Space

Enceladus is ripe for life. In one final pass through the icy moon’s liquid plumes, NASA’s Cassini spacecraft found molecular hydrogen, which indicates favourable conditions for life in Enceladus’s subsurface sea.

Giant Water Plume Detected Again on Jupiter Moon Europa
16th April 2017 | space.com | Space

What appears to be a huge plume of water vapor has again been spotted emanating from Jupiter’s icy moon Europa, boosting scientists’ confidence that the phenomenon is real.

Scientists measure brightness of the universe with NASA’s New Horizons spacecraft
16th April 2017 phys.org | Space

Images taken by NASA’s New Horizons mission on its way to Pluto, and now the Kuiper Belt, have given scientists an unexpected tool for measuring the brightness of all the galaxies in the universe, said a Rochester Institute of Technology researcher in a paper published this week in Nature Communications.

Asteroids Are Bad at Making Waves
15th April 2017 | space.com | Space

When an asteroid hits the middle of the ocean in Hollywood movies, it creates devastating waves that wipe out coastal cities. But new simulations reveal that real asteroids don’t make such a splash. That’s because the crash releases most of its energy hurling water up into the atmosphere, and very little on making waves.

A Freakishly Big Asteroid Is About to Zoom by Earth
15th April 2017 gizmodo.com | Space

Over the years, asteroids have gotten bad rap, probably because of that terrible Michael Bay movie or incessant stream of hyperbolic articles written about them. The truth is, asteroids are just hunks of rock hurling through space that aren’t actively seeking to destroy the human race. Later this month, one such non-apocalyptic asteroid will get close enough to Earth for our viewing pleasure. Even though it won’t do any damage, this is a damn big slice of space trash.

Could Moon Miners Use Railguns to Launch Ore into Space?
15th April 2017 | space.com | Space

The United States Navy fired a projectile at Mach 6 during a recent test with an electromagnetic railgun, suggesting that early ideas about using such tech to launch payloads from the lunar surface might not be so sci-fi after all.
