Scientists measure the evolving energy of a solar flare's explosive first minutes

Science Daily Astronomy - Fri, 2020-01-17 12:21
In 2017, a massive new region of magnetic field erupted on the sun's surface next to an existing sunspot. The powerful collision of magnetic energy produced a series of solar flares, causing turbulent space weather conditions at Earth. Scientists have now pinpointed for the first time exactly when and where the explosion released the energy that heated spewing plasma to energies equivalent to 1 billion degrees in temperature.

The core of massive dying galaxies already formed 1.5 billion years after the Big Bang

Science Daily Astronomy - Fri, 2020-01-17 10:47
The most distant dying galaxy discovered so far, more massive than our Milky Way -- with more than a trillion stars -- has revealed that the 'cores' of these systems had formed already 1.5 billion years after the Big Bang, about 1 billion years earlier than previous measurements revealed. The discovery will add to our knowledge on the formation of the Universe more generally, and may cause the computer models astronomers use, one of the most fundamental tools, to be revised.

Here and gone: Outbound comets are likely of alien origin

Science Daily Astronomy - Fri, 2020-01-17 09:43
Astronomers at the National Astronomical Observatory of Japan (NAOJ) have analyzed the paths of two objects heading out of the Solar System forever and determined that they also most likely originated from outside of the Solar System. These results improve our understanding of the outer Solar System and beyond.

Astronomers reveal interstellar thread of one of life's building blocks

Science Daily Astronomy - Wed, 2020-01-15 07:56
Phosphorus is an essential element for life as we know it. But how it arrived on the early Earth is something of a mystery. Astronomers have now traced the journey of phosphorus from star-forming regions to comets using the combined powers of ALMA and the European Space Agency's probe Rosetta. Their research shows where molecules containing phosphorus form, how this element is carried in comets, and how a particular molecule may have played a crucial role in starting life on Earth.

'Cold Neptune' and two temperate super-Earths found orbiting nearby stars

Science Daily Astronomy - Tue, 2020-01-14 09:09
A 'cold Neptune' and two potentially habitable worlds are part of a cache of five newly discovered exoplanets and eight exoplanet candidates found orbiting nearby red dwarf stars. The two potentially habitable planets are among the nearest stars to our own Sun, making them prime targets for observations by next-generation space- and land-based telescopes.

Connecting the dots in the sky could shed new light on dark matter

Science Daily Astronomy - Mon, 2020-01-13 17:56
Astrophysicists have come a step closer to understanding the origin of a faint glow of gamma rays covering the night sky. They found that this light is brighter in regions that contain a lot of matter and dimmer where matter is sparser -- a correlation that could help them narrow down the properties of exotic astrophysical objects and invisible dark matter.

Meteorite contains the oldest material on Earth: 7-billion-year-old stardust

Science Daily Astronomy - Mon, 2020-01-13 15:33
Scientists have discovered the oldest solid material on Earth: 7-billion-year-old stardust trapped inside a meteorite. This stardust provides evidence for a 'baby boom' of new stars that formed 7 billion years ago, contrary to thinking that star formation happens at a steady, constant rate.
