Source of hazardous high-energy particles located in the Sun

The source of potentially hazardous solar particles, released from the Sun at high speed during storms in its outer atmosphere, has been located for the first time by researchers at UCL and George Mason University, Virginia, U.S. These particles are highly charged and, if they...

Three elder sisters of the Sun with planets

An international team led by Prof. Dr. habil. Andrzej Niedzielski, an astronomer from the Nicolaus Copernicus University in Torun (Poland), has discovered yet another three extrasolar planets. These planets revolve around the stars that can be called elder sisters of our Sun. You can read...

Solar cells: Losses made visible on the nanoscale

Solar cells made of crystalline silicon achieve peak efficiencies, especially in combination with selective contacts made of amorphous silicon (a-Si:H). However, their efficiency is limited by losses in these contact layers. Now, for the first time, a team at Helmholtz-Zentrum Berlin (HZB) and the University...

Volunteers spot almost 100 cold brown dwarfs near our sun

Citizen scientists have spotted almost 100 of our sun’s nearest neighbors. In a new study, members of the public — including both professional scientists and volunteers — discovered 95 brown dwarfs (celestial objects too big to be considered planets and too small to be considered...

After the Sun Dies, It’ll Become a Stellar Crystal

Our sun may look like an eternal ball of burning gas, but one day it will die. This may sound like a bummer, especially for anything that’s living on Earth in a few billion years, but there is a bright side to the solar doom....

Why the sun will soon get dimmer

By 2050, our sun is expected to be unusually cool. It’s what scientists have termed a “grand minimum” — a particularly low point in what is otherwise a steady 11-year cycle. Over this cycle, the sun’s tumultuous heart races and rests. At its high point,...
