    Scientists get first glimpse of black hole eating star, ejecting high-speed flare

    An international team of astrophysicists led by a Johns Hopkins University scientist has for the first time witnessed a star being swallowed by a black hole and ejecting a flare of matter moving at nearly the speed of light. The finding reported Thursday in the journal Science tracks the star—about the size of our sun—as it shifts from its customary path, slips into the gravitational pull of a supermassive black hole and is sucked in, said Sjoert van Velzen, a Hubble fellow at Johns Hopkins.

    Dazzling diamonds

    Single stars are often overlooked in favour of their larger cosmic cousins — but when they join forces, they create truly breathtaking scenes to rival even the most glowing of nebulae or swirling of galaxies. This NASA/ESA Hubble Space Telescope image features the star cluster Trumpler 14. One of the largest gatherings of hot, massive and bright stars in the Milky Way, this cluster houses some of the most luminous stars in our entire galaxy.

    The huge gas cloud flying towards our galaxy could create 200 million new stars

    A giant gas cloud hurtling towards the Milky Way could form two million new stars when it finally collides with our galaxy. The discovery was made after astronomers managed to figure out the chemical composition of the Smith Cloud, a huge formation of gas approaching the edges of the Milky Way at a speed of around 193 miles per second.

    Tarantula Nebula: Hubble spots nine 'monster' stars with masses 100 times that of the Sun

    The Hubble Space Telescope has identified nine monster stars in outer space, all with a mass of over 100 times that of the Sun. The stars are part of the cluster R136, and have become the largest group of massive stars ever found. The star cluster is located 170,000 light years from Earth, and the findings will help astronomers learn about the origin of giant stars. The report was published in the Monthly Notices Of The Royal Astronomical Society.

    Faintest early-universe galaxy ever, detected and confirmed

    An international team of scientists has detected and confirmed the faintest early-Universe galaxy ever using the W. M. Keck Observatory on the summit on Maunakea, Hawaii. In addition to using the world's most powerful telescope, the team relied on gravitational lensing to see the incredibly faint object born just after the Big Bang. The results are being published in The Astrophysical Journal Letters today.

    Will the Great Attractor Destroy Us?

    Somewhere, in the deepest reaches of the cosmos, far from the safe confines of our home galaxy, the Milky Way, lies a monster. Slowly, inevitably, it is pulling. Over the course of billions of years, it draws us and everything near us closer to it. The only force that acts over such immense distance scales and through cosmic periods of time is gravity, so whatever it is, it's massive and unrelenting. We call it the Great Attractor, and until recently, its true nature has been a complete mystery. Note that it's still a mystery, just not a complete one.

    The Rocket Scientist Who Woke the Stars

    The nature of consciousness remains one of the great unsolved scientific mysteries. We have no clear handle on how consciousness manifests itself biologically or chemically or physically. We can’t even be certain that life, much less a functioning neural network, is a prerequisite for achieving that state. Panpsychism, the idea that consciousness is universal, has plenty of adherents and now one scientist with an unusual data set is saying that we need to take them seriously. That scientist, Greg Matloff, is not a crank.

This colossal wave of material - which was triggered when IC 2163 recently sideswiped another spiral galaxy dubbed NGC 2207 - produced dazzling arcs of intense star formation that resemble a pair of eyelids.

    6 More Mysterious Radio Signals Have Been Detected Coming From Outside Our Galaxy

    Back in March, scientists detected 10 powerful bursts of radio signals coming from the same location in space. And now researchers have just picked up six more of the signals seemingly emanating from the same region, far beyond our Milky Way. These fast radio bursts (FRB) are some of the most elusive and explosive signals ever detected from space - they only last milliseconds, but in that short period of time, they generate as much energy as the Sun in an entire day. But despite how powerful they are, scientists still aren't sure what causes them.

Stellar black holes form from the collapse of a large star. They can have a mass of 20 times that of of our sun or higher, and they consume anything that gets too close, including a star.

An energy beam that stabs out of galaxy M87 like a toothpick in a cocktail olive is pulling off the ultimate magic trick: seeming to move faster than the speed of light. Almost five times faster, in fact, as measured by the Hubble Space Telescope. This feat was first observed in 1995 in galaxy M87, and has been seen in many other galaxies since.

    A new kind of black hole has been found at the centre of the Milky Way – a find that may help explain the evolution of the phenomena. In research conducted by Japanese astronomers using the ALMA Observatory in northern Chile, a black hole 100,000 times the size of our sun was found within a molecular gas cloud. Its relatively small size means that it is the first to be identified as an intermediate-mass black hole (IMBH).

    Kronos: The eater of planets

    The Sun has been pretty good to us here on Earth over the last billion or so years. Sure we get the occasional solar storm and some deviations from ideal temperatures. But, by and large, we have a relatively supportive parent star. It’s nothing like those poor planets that orbit the star Kronos (HD 240430), located some 350 light-years away. On September 15, a team of Princeton astronomers posted a paper on the physics pre-print site arXiv.org that argues the star Kronos devoured over a dozen of its rocky inner planets during the course of its 4 billion year lifetime.

    Last week, astronomers using the PanSTARRS 1 telescope perched on the Haleakalā volcano on the island of Maui spotted what they believe is the first comet ever detected that does not orbit the sun. The comet, designated C/2017 U1, appears to have come from the direction of the constellation Lyra, and preliminary observations indicate it has a higher eccentricity than any known comet (1.1815), suggesting it is on a hyperbolic interstellar trajectory.

    In September 2014, when astronomer Iair Arcavi found a new supernova in the night sky, he didn’t think much of it. It looked like any other star that had just died and violently burst apart. The object had brightened some time ago, and now it was fading — a sign that the explosive event was coming to an end. Since the juiciest part seemed to be over, Arcavi abandoned the star in search of supernovae that had exploded more recently.

    It’s the 1st known interstellar asteroid

    A few weeks ago, we reported on a small object visiting from beyond our solar system. Now astronomers have scrutinized data from this object, which has been given the name `Oumuamua, and which must have traveled through space for millions of years before its chance encounter with our star system. The conclusion is that it’s a dark, reddish, highly-elongated rocky or high-metal-content object. And, indeed, it is the first known asteroid from interstellar space. These new results were published today (November 20, 2017) in the peer-reviewed journal Nature.
