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…
The correction of the problem will require the replacement of this unit. In order to perform this operation, it will be necessary to de-mate the launcher's…
Planets could be home to other forms of life, so the study of exoplanets ranks very high in contemporary astronomy. More than 300 planets are already known to…
Once considered rare and exotic objects, black holes are now known to exist throughout the Universe, with the largest and most massive found at the centres of…
For most of us, gold is only valuable if we possess it in large-sized pieces. However, the “bigger is better” rule isn’t the case for those interested in…
Beginning with their first NASA-funded project in 1971 and continuing through the 1990s, ECE Professors Charles Bostian and Warren Stutzman led Virginia Tech's…
Researchers at Umeå University in Sweden and the University of Maryland in the U.S. are now showing that there is a limit. When the size of the components…
We already know that comets played a significant role in ensuring that conditions were right for life on Earth. Most of the icy, small planetary bodies that…
In the first discovery of its kind, researchers from Canada, France and the United States have discovered an object that orbits around the Sun backwards, and…
Now Swedish researchers at Uppsala University are revealing that this methodology is worthless when it comes to practical problems. The article is published in…
Astronomical instruments needed to answer crucial questions, such as the search for Earth-like planets or the way the Universe expands, have come a step closer…
Nature’s own cosmic rays regularly produce more powerful particle collisions than those planned within the LHC, which will enable nature’s laws to be studied…
Now sealing the slender five-metre long GOCE (Gravity field and steady-state Ocean Circulation Explorer) spacecraft from view, the protective fairing will not…
A fork-like conductivity probe has sensed humidity rising and falling beside NASA's Phoenix Mars Lander, but when stuck into the ground, its measurements so…
An international team, led by astronomers at the MIT Haystack Observatory, has obtained the closest views ever of what is believed to be a super-massive black…
In the current online edition of Physical Review Letters, researchers from the Carnegie Institution's Geophysical Laboratory report changes in the melting…
The discovery of the doubly strange particle brings scientists a step closer to understanding exactly how quarks form matter and to completing the “periodic…
