Sounding rocket CLASP2 elucidates solar magnetic field

Cooperative operations between a solar observation satellite and a sounding-rocket telescope have measured the magnetic field strength in the photosphere and chromosphere above an active solar plage region. This is the first time that the magnetic field in the chromosphere has been charted all the way up to its top. This finding brings us closer to understanding how energy is transferred between layers of the Sun. ....

Early Mars is considered as an environment where life could possibly have existed. There was a time in the geological history of Mars when it could have been very similar to Earth and harbored life as we know it. In opposite to the current Mars conditions, bodies of liquid water, warmer temperature, and higher atmospheric pressure could have existed in Mars early history. Potential early forms of life on Mars should have been able to use accessible inventories of the red planet: derive energy from inorganic mineral sources and transform CO2 into biomass. Such living entities are rock-eating microorganisms, called chemolithotrophs , which are capable of transforming energy of stones to energy of li ....

The temporary breakdown of Earth s magnetic field 42,000 years ago sparked major climate shifts that led to global environmental change and mass extinctions, a new international study co-led by UNSW Sydney and the South Australian Museum shows.
This dramatic turning point in Earth s history - laced with electrical storms, widespread auroras, and cosmic radiation - was triggered by the reversal of Earth s magnetic poles and changing solar winds. ....

New observations of the first black hole ever detected have led astronomers to question what they know about the Universe s most mysterious objects.
Published today in the journal
Science, the research shows the system known as Cygnus X-1 contains the most massive stellar-mass black hole ever detected without the use of gravitational waves.
Cygnus X-1 is one of the closest black holes to Earth. It was discovered in 1964 when a pair of Geiger counters were carried on board a sub-orbital rocket launched from New Mexico. ....
