Scientists solve riddle of celestial archaeology
A decades old space mystery has been solved by an international team of astronomers led by Professor Martin Barstow of the University of Leicester and President-elect of the Royal Astronomical Society.
Far out: A giant exoplanet where none has been seen before
Humans have an eye for the familiar: for people, for civilizations, for planets and planetary systems that match what we have seen in the past. For this reason, as well as a few others, we rarely find something ...
The bow shock of Kappa Cassiopeiae, a massive, hot supergiant
(Phys.org) —Roguish runaway stars can have a big impact on their surroundings as they plunge through the Milky Way galaxy. Their high-speed encounters shock the galaxy, creating arcs, as seen in this newly ...
Mystery of planet-forming disks explained by magnetism
(Phys.org) —Astronomers say that magnetic storms in the gas orbiting young stars may explain a mystery that has persisted since before 2006.
Confirmed: Stellar behemoth self-destructs in a Type IIb supernova
Our Sun may seem pretty impressive: 330,000 times as massive as Earth, it accounts for 99.86 percent of the Solar System's total mass; it generates about 400 trillion trillion watts of power per second; and ...
Introducing Earth's bigger, older brother: planet Kapteyn b (w/ Video)
We now know of a potentially habitable planet five times the size of Earth that has existed for more than twice as long.
Researchers suggest changes to theories regarding neutron star crust structure
Magnetar formation mystery solved?
Magnetars are the super-dense remnants of supernova explosions. They are the strongest magnets known in the Universe—millions of times more powerful than the strongest magnets on Earth. A team of astronomers ...
How do you jumpstart a dead star?
It's a staple of science fiction, restarting our dying star with some kind of atomic superbomb. Why is our sun running out of fuel, and what can we actually do to get it restarted?
New tool for galactic archaeology
(Phys.org) —Reconstructing the history of our Galaxy has just become a whole lot easier, thanks to a team of international astronomers led by Dr Luca Casagrande from the Research School of Astronomy and ...
Nearest bright 'hypervelocity star' found: Speeding at 1 million mph, it probes black hole and dark matter
A University of Utah-led team discovered a "hypervelocity star" that is the closest, second-brightest and among the largest of 20 found so far. Speeding at more than 1 million mph, the star may provide clues ...
Two planets orbit nearby ancient star
An international team of scientists, led by astronomers at Queen Mary University of London, report of two new planets orbiting Kapteyn's star, one of the oldest stars found near the Sun. One of the newly-discovered ...
Astronomers harness the galaxy's biggest telescope to make most precise measurement of spinning star
(Phys.org) —An international team of astronomers has made a measurement of a distant neutron star that is one million times more precise than the previous world's best.
Fermi finds a 'transformer' pulsar
(Phys.org) —In late June 2013, an exceptional binary containing a rapidly spinning neutron star underwent a dramatic change in behavior never before observed. The pulsar's radio beacon vanished, while at ...
