Herschel discovers some of the youngest stars ever seen
(Phys.org) —Astronomers have found some of the youngest stars ever seen, thanks to the Herschel space observatory, a European Space Agency mission with important NASA contributions.
Researchers develop model for identifying habitable zones around star
Researchers searching the galaxy for planets that could pass the litmus test of sustaining water-based life must find whether those planets fall in a habitable zone, where they could be capable of having ...
Black hole naps amidst stellar chaos
(Phys.org) —Nearly a decade ago, NASA's Chandra X-ray Observatory caught signs of what appeared to be a black hole snacking on gas at the middle of the nearby Sculptor galaxy. Now, NASA's Nuclear Spectroscopic ...
When galaxies eat galaxies: Gravitational lenses suggest big collisions make galaxies denser
(Phys.org)—Using gravitational "lenses" in space, University of Utah astronomers discovered that the centers of the biggest galaxies are growing denser – evidence of repeated collisions and mergers by ...
Most distant blazar is a high-energy astrophysics puzzle
(Phys.org) —Blazars are the brightest of active galactic nuclei, and many emit very high-energy gamma rays. New observations of the blazar known as PKS 1424+240 show that it is the most distant known source ...
Using the Sun to illuminate a basic mystery of matter
Antimatter has been detected in solar flares via microwave and magnetic-field data, according to a presentation by NJIT Research Professor of Physics Gregory D. Fleishman and two co-researchers at the 44th ...
Astronomers discover galaxies near cosmic dawn (Update)
(Phys.org)—A team of astronomers led by the California Institute of Technology (Caltech) has used NASA's Hubble Space Telescope to discover seven of the most primitive and distant galaxies ever seen.
Evidence of forming planet discovered 335 light years from Earth
An international team of scientists led by a Clemson University astrophysicist has discovered new evidence that planets are forming around a star about 335 light years from Earth.
Liquid spacetime: A very slippery superfluid, that's what spacetime could be like
What if spacetime were a kind of fluid? This is the question tackled by theoretical physicists working on quantum gravity by creating models attempting to reconcile gravity and quantum mechanics. Some of ...
Hubble sees asteroid spouting six comet-like tails
(Phys.org) —Astronomers using NASA's Hubble Space Telescope have identified what they can only describe as a never-before-seen "weird and freakish object" in the asteroid belt that looks like a rotating ...
Rare galaxy found furiously burning fuel for stars
Astronomers have found a galaxy turning gas into stars with almost 100 percent efficiency, a rare phase of galaxy evolution that is the most extreme yet observed. The findings come from the IRAM Plateau de ...
Inside the Milky Way: One step closer to figuring out the mysteries of our galaxy's core
Is matter falling into the massive black hole at the center of the Milky Way or being ejected from it? No one knows for sure, but a UC Santa Barbara astrophysicist is searching for an answer.
Astronomers dissect the aftermath of a supernova
In research published today in the Astrophysical Journal, an Australian led team of astronomers has used radio telescopes in Australia and Chile to see inside the remains of a supernova.
Dating our galaxy's dormant volcano
(Phys.org) —A dormant volcano—a supermassive black hole—lies at the heart of our galaxy. Fresh evidence suggests that it last erupted two million years ago.
