Young stars ejecting plasma could give us clues into the Sun’s past Kyoto, Japan — Down here on Earth we don’t usually notice, but the Sun is frequently ejecting huge masses of plasma into space. These are called coronal mass ejections (CMEs). They often occur together with sudden brightenings called flares, and sometimes extend far enough to disturb Earth’s magnetosphere, generating space weather phenomena including auroras or geomagnetic storms, and even damaging power grids on occasion. Scientists believe that when…
According to a paper by professional astronomers, expected to be published today online by Astrophysical Journal Letters, the asteroid was eight to 13 meters…
Though it was once believed that all asteroids are giant pieces of solid rock, later hypotheses have it that some are actually a collection of small…
Now, astronomers using clever techniques to cull the data archives of NASA's Hubble Space Telescope have added 14 new TNOs to the catalog. Their method…
PLA2 enzymes exist as secreted forms and cytosolic forms. The cytosolic or cPLA2 enzymes appear to play a key role in the pathway leading to the formation of…

In comets as well as in interstellar clouds, the precursor molecule of water is the positively charged hydronium ion H3O+. This molecular ion can be detected…
In Pardorama, situated 2600 m above sea level, in Ischgl/Tyrol, European researchers in the field of quantum matter will meet to discuss the newest findings in…
RNA sequencing is used to compare differences in gene expression to identify those genes that switched on or off when, for instance, a particular disease is…
The Radio Aurora Explorer (RAX) is slated for launch Nov. 19 from Kodiak, Alaska. Its primary mission is to study how plasma instabilities in the highest…
Liquid water has interacted with the Martian surface throughout Mars' history, measurements by NASA's Phoenix Mars Lander suggest. The findings, published in…
Faint traces of the supernova, found in a meteorite, account for the mysterious variations in the chemical fingerprint of chromium found from one planet and…
The existence of Dark Matter particles in the Sun's interior seems inevitable, despite dark matter never having been observed (there or elsewhere), despite…
Behind every coincidence lies a plan – in the world of classical physics, at least. In principle, every event, including the fall of dice or the outcome of a…
X-rays are the medium of choice for many scientific studies. When you shine them on a sample, they literally shed light on the material’s structure, providing…
Published in this week’s issue of Nature,* the new research raises several intriguing questions about the fundamental physics of this exciting material and…
