Gamma-ray Telescope Ready for Prime Time
Jan 21, 2019 (SPX)
Known formally as the prototype Schwarzchild-Couder Telescope, the new telescope is a working, high-end test bed for technologies to be used in the Cherenkov Te...
Observations of a rare hypernova complete the picture of the death of the massive stars
Jan 18, 2019 (SPX)
An international group of astronomers has published a detailed study of the death of a high-mass star that produced a gamma-ray burst (GRB) and a hypernova, in ...
High-speed supernova reveals earliest moments of a dying star
Jan 18, 2019 (SPX)
A relativistic jet is a very powerful phenomena which involves plasma jets shooting out of black holes at close to the speed of light, and can extend across mil...
Hubble's Wide Field Camera 3 to resume operations
Jan 17, 2019 (SPX)
Shortly after noon EST on Jan. 8, software installed on the Wide Field Camera 3 detected that some voltage levels within the instrument were out of the predefin...
Innovative research uses remote radio telescopes to detect cosmic rays
Jan 17, 2019 (SPX)
The project is the first coupling of a particle detector with the MWA, located in Western Australia's Mid-West region about 800 km north of Perth, and will allo...
Using light to achieve computational logic
Jan 17, 2019 (SPX)
Computers need an upgrade. From smartwatches to data centers, all computers feature similar kinds of components, including processors and memory. These semicond...
From volcanoes on Mars to scarps on Mercury - how places on other worlds get their names
Jan 16, 2019 (The Conversation)
The IAU's achievements during its first few decades include resolving contradictory sets of names given to features on the Moon and Mars by rival astronomers du...
New technique more precisely determines the ages of stars
Jan 15, 2019 (SPX)
Current star-dating techniques, based on assessments of stars in the prime or main sequence of their lives that have begun to die after exhausting their hydroge...
Astronomers find signatures of a 'messy' star that made its companion go supernova
Jan 15, 2019 (SPX)
These latter events can happen in binary star systems, where two stars attempt to share dominion. While the exploding star gives off lots of evidence about its ...
Next generation photonic memory devices are light-written, ultrafast and energy efficient
Jan 15, 2019 (SPX)
Ultra-short (femtosecond) light pulses allows data to be directly written in a magnetic memory in a fast and highly energy-efficient way. Moreover, as soon as t...
Physicists find new ways to manipulate light, paving way for quantum tech
Jan 14, 2019 (UPI)
The research, detailed in the journal Physical Review Letters, could pave the way for new quantum technologies and telecommunication systems. While experimentin...
Control over Russia's only space telescope lost
Jan 14, 2019 (Sputnik)
"We're trying to fix the problem [...], there are different communications systems; some of them work, some do not work. We still receive some signals. Such fai...
Russia loses control of only space telescope
Jan 14, 2019 (AFP)
The incident is the latest setback for Russia's debt-laden space industry, which in recent years has suffered the loss of spacecraft, satellites, and a failed m...
Team of telescopes finds X-ray engine inside mysterious supernova
Jan 14, 2019 (ESA)
The ATLAS telescope in Hawaii first spotted the phenomenon, since then named AT2018cow, on 16 June. Soon after that, astronomers all over the world were pointin...
Thousands of stars turning into crystals
Jan 10, 2019 (SPX)
Observations have revealed that dead remnants of stars like our Sun, called white dwarfs, have a core of solid oxygen and carbon due to a phase transition durin...
First evidence of gigantic remains from star explosions
Jan 10, 2019 (SPX)
A white dwarf is the dead core of a star. When it is paired with a companion star in a binary system, it can potentially produce a nova explosion. If the condit...
Milky Way-sized galaxy lacking galactic neighbors
Jan 10, 2019 (SPX)
The study examined the satellite galaxies of Messier 94, or M94, a galaxy similar in size to our Milky Way. Researchers have long known the Milky Way has about ...
NRAO identifies 100,000 star factories in 74 galaxies across the universe
Jan 10, 2019 (SPX)
A vast, new research project with the Atacama Large Millimeter/submillimeter Array (ALMA), known as PHANGS-ALMA (Physics at High Angular Resolution in Nearby Ga...
Probing the magnetar at the center of our galaxy
Jan 10, 2019 (SPX)
The new research provides clues that magnetars like this one, lying in close proximity to a black hole, could perhaps be linked to the source of "fast radio bur...
Gaia reveals how Sun-like stars turn solid after their demise
Jan 10, 2019 (ESA)
This process of solidification, or crystallisation, of the material inside white dwarfs was predicted 50 years ago but it wasn't until the arrival of Gaia that ...
