Rare star explosion reveals hidden black hole in our galaxy
Astronomers have spotted a rare X-ray star explosion near the center of our Milky Way galaxy, revealing a previously unknown black hole munching on gas from a neighboring sun-like star.
NASA's Swift satellite made the cosmic find last month when it detected a new and rapidly brightening X-ray source a few degrees from the galactic center of the Milky Way. Astronomers identified the outburst as a short-lived bright X-ray nova, which is produced when a stream of gas rushes toward either a neutron star or a black hole. Unlike a supernova, which is the explosive death of a star, novas are smaller explosions that do not completely destroy a star.
The black hole is thought to be 20,000 to 30,000 light-years away in the galaxy's inner region. Astronomers, who named the bright X-ray nova Swift J1745-26 after its coordinates in space, said witnessing such an event is rare.
"Bright X-ray novae are so rare that they're essentially once-a-mission events and this is the first one Swift has seen," Neil Gehrels, of NASA's Goddard Space Flight Center in Greenbelt, Md., said in a statement. "This is really something we've been waiting for."?[Stealth Black Hole Revealed by Nova (Video)]
At its peak in high-energy X-rays on Sept. 18, the nova reached an intensity equivalent to that of the?Crab Nebula. While these rays dimmed, the nova brightened in lower-energy emissions detected by Swift's X-ray Telescope through at least the beginning of October, according to NASA.
Additional observations suggested that a black hole was at the center of this radiation flare-up.
"The pattern we're seeing is observed in X-ray novae? where the central object is a black hole," Boris Sbarufatti, an astrophysicist from Milan's Brera Observatory who currently is working with the Swift team, said in an Oct. 5 NASA statement. "Once the X-rays fade away, we hope to measure its mass and confirm its black hole status."
The Swift team believes the black hole is part of a low-mass X-ray binary system, in which gas flows from a star into a disk around the?black hole, spiraling inward and heating up greatly as it heads toward the center.
But a cosmic glitch can disrupt the steady flow of gas and cause it to accumulate in the outer portion of the disk like water behind a dam, according to NASA scientists. After enough gas has built up (often over several decades), the disk can switch to a hotter, more ionized state that sends the gas rushing toward the center of the black hole, creating the X-ray nova.

89% Robot & Frank
All Critics (80) | Top Critics (31) | Fresh (71) | Rotten (9)
"Robot & Frank" hits all the right notes - romantic, fantastic, tragic and sweet.
There's a warm and poignant interplay between the co-stars.
Langella ... is tremendous.
It may not seem like an even playing field pitting an actor as powerfully intense as Frank Langella opposite a robot, but that's the game plan behind the waywardly endearing, slightly futuristic fantasy Robot & Frank.
Much of Robot & Frank is (frankly) resistible, including the climactic narrative twist, but there is also a likeable oddness that transcends the sentimental contrivance.
An endearing movie about a human and his mechanical new buddy.
Deserves credit for bringing comic fantasy close to sensitive reality
If Miranda July tackled an episode of Tales of the Unexpected the results might be something close to what's on offer here.
Langella provides a formidable central presence, both stubborn and endearing, while Sarsgaard injects warmth and humanity into Robot.
An hysterically funny, breathlessly paced and moving meditation on old age and existence, topped by an award-worthy turn from Frank Langella. One of the year's best.
Jake Schreier and scriptwriter Christopher Ford go well beyond the initial fun of the robot conceit to craft a thoughtful film musing on both the ageing process and our relationship with technology.
A little gem of a movie about aging and obsolescence that is also a very modest sci-fi cautionary tale.
... a marvel of the highest order. Robot and Frank manages to seamlessly blend comedy, science fiction and drama into a film that is hilarious, truly original and utterly heartfelt
This blend of sentiment and genre fancy is not unlike something Ray Bradbury might have contrived for The Magazine of Fantasy & Science Fiction.
Robot & Frank is an airy, engaging flight of fancy. It's also part caper film, part character study, and part allegory about aging. Robot & Frank shouldn't work, but it does.
..never hits the easy and obvious beats of a buddy comedy; there's no sentimental bonding between man and mecha man. Similarly, though it feints toward romance, the relationship ... resolves in an unexpectedly bittersweet way.
"Robot & Frank" is a study of a man who lives with his past mistakes but can't shake how truly alive they made him feel when he was making them, regardless of what they cost him.
Hodgepodge of moods built around an unlikely story of friendship between a man and his service robot, the film carries itself confidently, with occasional moments of significant emotion.
They get the robot right, with fluid movement (by dancer Rachael Ma) and canned warmth in its user-friendly voice (performed by Peter Sarsgaard).
What a weird, winning little movie is Robot & Frank.
The chief spectacle here -- and it's a good one -- is Langella in gruff, curdled mode, an underappreciated master actor slipping seamlessly into a bespoke role.
"Robot & Frank" is so endearing it's easy to forget it's science fiction.
The movie is sweet and agreeably unambitious, derailed only by an egregious third-act twist.

Father of bone marrow transplant is dead at 92
PORTLAND, Ore. (AP) ? E. Donnall Thomas, a physician who pioneered bone marrow transplants and later won the 1990 Nobel Prize in medicine, has died in Seattle at age 92.
The Fred Hutchison Cancer Research Center announced the death Saturday. A spokesman says the cause was heart disease.
Thomas' groundbreaking work is among the greatest success stories in the treatment of leukemia. Bone marrow transplantation and its sister therapy, blood stem cell transplantation, have improved the survival rates for some blood cancers to upward of 90 percent from almost zero.
This year, about 60,000 transplants will be performed worldwide.
Larry Corey, the president of the research center, says Thomas will forever be known as the father of bone marrow transplantation, but to his colleagues he will be remembered as a colleague and a mentor.
