Dead star and distant black holes dazzle in X-rays
(Phys.org) —Two new views from NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, showcase the telescope's talent for spying objects near and far. One image shows the energized remains of a dead star, ...
A galaxy with two hearts
This new Hubble image shows the spiral galaxy Messier 83, otherwise known as the Southern Pinwheel Galaxy. One of the largest and closest barred spirals to us, this galaxy is dramatic and mysterious; it has ...
Surprising new class of 'hypervelocity stars' discovered escaping the galaxy
An international team of astronomers has discovered a surprising new class of "hypervelocity stars" – solitary stars moving fast enough to escape the gravitational grasp of the Milky Way galaxy.
A rare crash at the Milky Way's core
(Phys.org) —University of Michigan astronomers could be the first to witness a rare collision expected to happen at the center of the galaxy by spring.
Quasars illuminate swiftly swirling clouds around galaxies
(Phys.org) —A new study of light from quasars has provided astronomers with illuminating insights into the swirling clouds of gas that form stars and galaxies, proving that the clouds can shift and change ...
Swift catches X-ray action at Milky Way's center
(Phys.org) —Recent observations by NASA's Swift spacecraft have provided scientists a unique glimpse into the activity at the center of our galaxy and led to the discovery of a rare celestial entity that ...
Death by black hole in small galaxy?
(Phys.org) —A bright, long-duration flare may be the first recorded event of a black hole destroying a star in a dwarf galaxy. The evidence comes from two independent studies using data from NASA's Chandra ...
Dwarf galaxies give clues to origin of supermassive black holes
(Phys.org) —Poring through data from a large sky survey, astronomers have found more than 100 small, dwarf galaxies with characteristics indicating that they harbor massive black holes feeding on surrounding ...
Fermi observatory makes first gamma-ray study of a gravitational lens
An international team of astronomers, using NASA's Fermi observatory, has made the first-ever gamma-ray measurements of a gravitational lens, a kind of natural telescope formed when a rare cosmic alignment ...
Birth of black hole kills the radio star
Astronomers led by a Curtin University researcher have discovered a new population of exploding stars that "switch off" their radio transmissions before collapsing into a Black Hole.
Find black holes while you're on the bus
'Radio Galaxy Zoo', launching today, is a new 'citizen science' project that lets anyone become a cosmic explorer.
New work gives credence to theory of universe as a hologram
Image: Hubble sees a bizarre cosmic rarity: NGC 660
This new Hubble image shows a peculiar galaxy known as NGC 660, located around 45 million light-years away from us.
Creation of entanglement simultaneously gives rise to a wormhole
Quantum entanglement is one of the more bizarre theories to come out of the study of quantum mechanics—so strange, in fact, that Albert Einstein famously referred to it as "spooky action at a distance."
