Stellar pulsations distribute key ingredient for life

As Carl Sagan famously said, "We're made of star stuff"—but how do stars distribute their essential "stuff" for life into space? NASA's telescope on an airplane, SOFIA, is finding some answers by watching pulsating stars ...

Record EOS measurement pressures shed light on stellar evolution

Using the power of the National Ignition Facility (NIF), the world's highest-energy laser system, researchers at Lawrence Livermore National Laboratory (LLNL) and an international team of collaborators have developed an experimental ...

Ammonia-rich hail sheds new light on Jupiter's weather

New Juno results suggest that the violent thunderstorms taking place in Jupiter's atmosphere may form ammonia-rich hail, or 'mushballs,' that play a key role in the planet's atmospheric dynamics. This theory, developed using ...

Uncovering our solar system's shape

Scientists have developed a new prediction of the shape of the bubble surrounding our solar system using a model developed with data from NASA missions.

Researchers explore the origins of stars rich in phosphorus

The journal Nature Communications has published the discovery of a new type of star that is very rich in phosphorus, which could help to explain the origin of phosphorous in our galaxy. This achievement has been made by astronomers ...

VLBA finds planet orbiting small, cool star

Using the supersharp radio "vision" of the National Science Foundation's continent-wide Very Long Baseline Array (VLBA), astronomers have discovered a Saturn-sized planet closely orbiting a small, cool star 35 light-years ...

CTCV J2056-3014 is an unusual polar, study finds

Astronomers have investigated a nearby cataclysmic variable system known as CTCV J2056-3014 using ESA's XMM-Newton satellite. Results of the study, presented in a paper published July 28 on the arXiv pre-print repository, ...

Black hole fails to do its job

Astronomers have discovered what can happen when a giant black hole does not intervene in the life of a galaxy cluster. Using NASA's Chandra X-ray Observatory and other telescopes they have shown that passive black hole behavior ...

ALMA captures stirred-up planet factory

Planet-forming environments can be much more complex and chaotic than previously expected. This is evidenced by a new image of the star RU Lup, made with the Atacama Large Millimeter/submillimeter Array (ALMA).

Unequal neutron-star mergers create unique 'bang' in simulations

When two neutron stars slam together, the result is sometimes a black hole that swallows all but the gravitational evidence of the collision. However, in a series of simulations, an international team of researchers including ...
