Loops cold could help solve the mystery of the solar corona

The surface of the Sun is a very cold place. When compare it with the crown, the upper atmosphere of the Sun, which is almost 400 times hotter. This large temperature difference has long been a mystery, but a newly discovered feature in the Sun's magnetic field could help us get to the bottom of it.

The Sun's magnetic field tangled includes huge loops forming an arc from the surface to the crown. We can see the bright loops because the surface plasma flows along its curves.

NASA discovers two planets around a star cluster

U.S. scientists have found indication for the first time that there are planets that can form and survive around stars similar to the sun regardless of forming part of dense clusters of stars, NASA announced.

Astronomers discovered two orbits similar to Jupiter in the Beehive Cluster, a group of about 1,000 stars that seem to swarm around a common center.

"This has been a great puzzle for planet hunters," said Sam Quinn, a doctoral student in Astronomy at Georgia State University in Atlanta, and author of the paper describing the results.

Kemble's Cascade

Kemble's Cascade is an asterism containing about 20 stars, of magnitudes between 5 and 10, and associated, extending a distance of more than five times the full moon. At the end of the cascade, as if it were a stellar lake, we can find the open cluster NGC 1502.

An asterism is a recognized set of stars that appear to form a figure but not one of the 88 official constellations. For example, one of the most famous asterisms is The Chariot located in the constellation Ursa Major. For Kemble's Cascade, this is located in the constellation of the Giraffe and is easily visible with binoculars.
