Image: Hubble views the whirling disk of NGC 4526
This neat little galaxy is known as NGC 4526. Its dark lanes of dust and bright diffuse glow make the galaxy appear to hang like a halo in the emptiness of space in this image from the NASA/ESA Hubble Space ...
Most metal-poor star hints at universe's first supernovae
A team of researchers, led by Miho N. Ishigaki, at the Kavli IPMU, The University of Tokyo, pointed out that the elemental abundance of the most iron-poor star can be explained by elements ejected from supernova ...
Animals first flex their muscles
An unusual new fossil discovery of one of the earliest animals on earth may also provide the oldest evidence of muscle tissue – the bundles of cells that make movement in animals possible.
Image: The twisted shockwaves of an exploded star
Discovered on 5 September 1784 by astronomer William Herschel, the Veil Nebula was once a star. Now it is a twisted mass of shock waves that appears six times larger than the full Moon in the sky.
Magnetar discovered close to supernova remnant Kesteven 79
(Phys.org) —Massive stars end their lives with a bang, exploding as supernovas and releasing massive amounts of energy and matter. What remains of the star is a small and extremely dense remnant: a neutron ...
Strange supernova is 'missing link' in gamma-ray burst connection
Astronomers using the National Science Foundation's Very Large Array (VLA) have found a long-sought "missing link" between supernova explosions that generate gamma-ray bursts (GRBs) and those that don't. ...
Darwin's dilemma resolved: Biologists measure evolution's Big Bang
A new study led by Adelaide researchers has estimated, for the first time, the rates of evolution during the "Cambrian explosion" when most modern animal groups appeared between 540 and 520 million years ...
Explosive volcanoes fueled by water, researchers find
University of Oregon geologists have tapped water in surface rocks to show how magma forms deep underground and produces explosive volcanoes in the Cascade Range.
Pulse of a dead star powers intense gamma rays
(Phys.org) —Our Milky Way galaxy is littered with the still-sizzling remains of exploded stars.
Project turns to sensors in sewers to catch bomb-makers
Ultrasonic hammer sets off tiny explosions
Giving new meaning to the term "sonic boom," University of Illinois chemists have used sound to trigger microscopic explosions.
AVERT team shows autonomous extraction system for vehicles
Researchers use scientific guns to induce shock waves into explosive materials to study their performance, properties
As the U.S. Nuclear Deterrent ages, one essential factor in making sure that the weapons will continue to perform as designed is understanding the fundamental properties of the high explosives that are part ...
Japan's volcanoes: Could Fuji be next?
The sudden eruption of Mount Ontake over the weekend, which is believed to have killed at least 31 people, was a reminder of Japan's vulnerability to its many active volcanoes.
