Astronomers have witnessed a cosmic tug of war between Haley's Coronet and its neighboring dwarf galaxy. The gravitational tussle is one the smaller galaxy is bound to lose. That could ultimately result in a merger between the two.

SpaceX scrubs record-breaking Falcon Heavy rocket launch (video)

Olympus Could Have Been a Giant Volcanic Island in an Ancient Martian Ocean
Olympus Mons, located at the northwest edge of the Tharsis Montes region on Mars, was appropriately named. Based on readings obtained by the Mars Orbiter Laser Altimeter (MOLA), an instrument aboard NASA’s Mars Global Surveyor (MGS), this mountain is the tallest in the Solar System, standing 21.9 km (13.6 mi) tall – about two and a half times the height of Mount Everest (8.85 km; 5.5 mi). According to current estimates, this extinct shield volcano formed during Mars’ Hesperian Period (ca. 3.7 to 3 billion years ago), which was characterized by widespread volcanic activity and catastrophic flooding.
Need To Image An Asteroid Close Up? There’s an AMIGO For That.
There are so many asteroids. Just in our own backyard, we’ve found over 30,000 Near Earth asteroids. Exploring them using traditional methods and launching a custom-made mission, like Hayabusa or OSIRIS-REx, would almost certainly be cost-prohibitive. So how can we assess whether they would make good targets for early asteroid mining missions? Ground imaging can help, but there’s nothing like being on-site on one of these asteroids to get a sense of what they are made of. Those visits would be much easier if we mass-produced the Asteroid Mobile Imager and Geologic Observer (AMIGO).
A Gamma Ray Burst Lasted So Long it Triggered a Satellite Twice
Gamma Ray Bursts (GRBs) are the most powerful astrophysical phenomena in the universe. For a span of seconds to a few minutes, they can be the most powerful high-energy event in the sky, shining across billions of light years. But recently astronomers detected a GRB that lasted more than a thousand seconds, with two blasts of gamma rays that triggered the Fermi Gamma Ray Burst Monitor. It’s such a strange cosmic event that astronomers aren’t sure what caused it, but they do have a possible idea.
Witnesses Play Up the Alien Angle at Congressional UFO Hearing
Three former insiders who have played a role in dealing with UFOs — or as they’ve now come to be known, unidentified anomalous phenomena — say the U.S. military knows more than what it’s been telling lawmakers about encounters with potentially alien technology.
