Rare first moment of stellar explosion captured by amateur astronomer

Thu, 22 Feb 18 00:14:20 -0800

An amateur astronomer testing his new camera captures the moment a supernova became visible in the night sky, which has helped an international team of researchers to test their theory about the beginning stages of a stellar explosion.

Amateur astronomer captures rare first light from massive exploding star

Wed, 21 Feb 18 00:02:30 -0800

First light from a supernova is hard to capture; no one can predict where and when a star will explode. An Argentinian amateur astronomer has now captured on film this first light, emitted when the exploding core hits the star's outer layers: shock breakout. Subsequent observations by UC Berkeley astronomers using the Lick and Keck observatories helped identify it as a Type IIb supernova that slimmed down from 20 to 5 solar masses before exploding.

Amateur astronomer captures rare first light of massive exploding star

Wed, 21 Feb 18 00:08:30 -0800

An amateur astronomer in Argentina captured images of a distant galaxy before and after the supernova's 'shock breakout' - when a supersonic pressure wave from the exploding core of the star hits and heats gas at the star's surface to a very high temperature, causing it to emit light and rapidly brighten. Victor Buso's chances of such a discovery, his first supernova, is estimated at one in 10 million or perhaps even as low as one in 100 million.

Astronomers discover S0-2 star is single and ready for big Einstein test

Wed, 21 Feb 18 00:15:10 -0800

A team of astronomers led by Devin Chu, a UCLA scientist from Hawaii, has found that S0-2 does not have a significant other after all, or at least one that is massive enough to get in the way of critical measurements that astronomers need to test Einstein's Theory of General Relativity. Up until now, it was thought that S0-2 may be a binary, a system where two stars circle around each other.

No relation between a supermassive black hole and its host galaxy!?

Tue, 20 Feb 18 00:05:30 -0800

Using ALMA to observe an active galaxy with a strong ionized gas outflow from the galactic center, a team led by Dr. Toba of ASIAA (Taiwan) has obtained a result making astronomers even more puzzled -- the team clearly detected CO gas associated with the galactic disk, yet they have also found that the CO gas which settles in the galaxy is not affected by the strong ionized gas outflow launched from the galactic center.

Shedding (high-power laser) light on the plasma density limit

Tue, 20 Feb 18 00:09:00 -0800

Researchers theoretically proposed the existence of density limit for hole boring by laser light on matter. They derived the maximum plasma density as a function of laser intensity, where hole boring stops and plasma blowout occurs. Theory and simulation of an ultra-high-pressure plasma state, wherein plasma's density pushes light back in the direction of the laser source, contribute to fundamental understanding, and provided grounding for applications such as laser-induced nuclear fusion.

Some black holes erase your past

Tue, 20 Feb 18 00:11:40 -0800

Physicists insist on determinism: your past and present determine your future uniquely, per Einstein's equations of general relativity. They call this strong cosmic censorship. A UC Berkeley mathematician found some types of black holes -- charged, non-rotating objects in an expanding universe -- that allow an observer inside the black hole to travel across a horizon into a place where the past is obliterated and there are an infinite number of possible futures for every initial state.

Astronomers reveal secrets of most distant supernova ever detected

Mon, 19 Feb 18 00:05:20 -0800

An international team of astronomers led by the University of Southampton has confirmed the discovery of the most distant supernova ever detected -- a huge cosmic explosion that took place 10.5 billion years ago, or three-quarters the age of the Universe itself.

This brings the total number of new exoplanets found with the K2 mission up to almost 300. The new results are to be published in the Astronomical Journal.

The search for dark matter: Axions have ever fewer places to hide

Wed, 14 Feb 18 00:03:40 -0800

If they existed, axions -- one of the candidates for particles of the mysterious dark matter -- could interact with the matter forming our world, but they would have to do this to a much, much weaker extent than it has seemed up to now. New, rigorous constraints on the properties of axions have been imposed by an international team of scientists responsible for the nEDM experiment.

Star architecture and its impact on the city

Mon, 12 Feb 18 00:09:40 -0800

The Guggenheim Museum by star architect Frank Gehry led to an economic boom in the Spanish city of Bilbao. This 'Bilbao Effect' is appealing to many urban planners and politicians who look to better position their cities in economic and social terms by building exceptional architectural projects. Researchers at the Technical University of Munich (TUM) have studied three projects to investigate whether or not the desired effects materialize.

Recreating liver tumors as organoids for faster, more accurate drug screening

Wed, 07 Feb 18 00:15:20 -0800

A major challenge in developing liver cancer drugs is that preclinical testing occurs in tumor models that do not accurately reflect human tumor features, causing drug candidates to later fail in clinical testing. Now, Singaporean researchers have grown organoids from liver tumors on specially engineered 3-D scaffolds. These organoids replicate important features of the original tumor, including genetic changes and intra-tumor heterogeneity, and could serve as tumor avatars for high-throughput drug screening.

Lone star ticks not guilty in spread of Lyme disease

Wed, 31 Jan 18 00:12:30 -0800

The bacteria that cause Lyme disease are transmitted to humans primarily by the blacklegged tick (Ixodes scapularis). Often presumed guilty by association is the lone star tick (Amblyomma americanum). However, a new review of three decades' worth of research concludes the latter should be exonerated: While lone star ticks are guilty of transmitting bacteria that cause several human illnesses, the scientific evidence says Lyme disease is not one of them.

Galaxies that feed on other galaxies

Wed, 31 Jan 18 00:11:50 -0800

Interstellar fullerenes may help find solutions for earthly matters

Mon, 29 Jan 18 00:14:40 -0800

The nearest interstellar clouds with confirmed fullerene presence are about 1,000 light years away from Earth. Electromagnetic spectra of 19 distant stars were provided by the VLT telescope in Chile, one of the largest in the world. The authors found fullerenes which left traces - absorption lines in certain frequencies.

Mind your speed: A magnetic brake on proton acceleration

Mon, 29 Jan 18 00:11:10 -0800

An international research team led by Osaka University studied high-energy protons emitted from laser-bombarded solids. Recent studies found that higher laser intensities failed to boost the proton energies as much as predicted. By experiment and simulation, the researchers showed that magnetic fields, generated by electrons ejected from the target, inhibited the electric fields responsible for proton acceleration. Strategies for minimizing this inhibition were explored. Higher-energy protons are needed in neutron spallation and possible cancer therapies.
