Sun's close-up reveals atmosphere hopping with highly energetic particles

Science Daily Astronomy - Wed, 2019-12-04 14:59
Outbursts of energetic particles that hurtle out from the sun and can disrupt space communications may be even more varied and numerous than previously thought, according to results from the closest-ever flyby of the sun.

Hidden giant planet revealed around tiny white dwarf star

Science Daily Astronomy - Wed, 2019-12-04 14:58
The first evidence of a giant planet orbiting a dead white dwarf star has been found in the form of a disc of gas formed from its evaporating atmosphere.

Parker Solar Probe traces solar wind to its source on sun's surface: coronal holes

Science Daily Astronomy - Wed, 2019-12-04 14:58
New data from the Parker Solar Probe, which got closer to the sun than any other spacecraft, allowed physicists to map the source of a major component of the solar wind that continually peppers Earth. The slow solar wind seems to emerge from coronal holes along the sun's equator. Data also reveal strange magnetic field reversals that could be accelerating solar wind particles, and an unexpectedly dense shroud of comet dust around the sun.

NASA's Parker Solar Probe sheds new light on the sun

Science Daily Astronomy - Wed, 2019-12-04 14:49
Since its 2018 launch, NASA's Parker Solar Probe (record-holder for closest-ever spacecraft to the Sun) has finished three of 24 planned passes through never-before-explored parts of the Sun's atmosphere. Four new articles describe what scientists have learned from its unprecedented exploration, and what they look forward to learning next.

Exoplanet-hunting mission catches a natural comet outburst in unprecedented detail

Science Daily Astronomy - Tue, 2019-12-03 16:43
Astronomers have captured a clear start-to-finish image sequence of an explosive emission of dust, ice and gases during the close approach of comet 46P/Wirtanen in late 2018.

Detecting solar flares, more in real time

Science Daily Astronomy - Tue, 2019-12-03 13:38
Computers can learn to find flares and other events in vast streams of solar images to help forecasters issue timely alerts, according to a new study. The machine-learning technique searches satellite data for features significant for space weather. Changing conditions on the Sun can affect various technologies on Earth, blocking radio communications, damaging power grids, and diminishing navigation system accuracy.

Gas giant composition not determined by host star

Science Daily Astronomy - Tue, 2019-12-03 11:45
A surprising analysis of the composition of gas giant exoplanets and their host stars shows that there isn't a strong correlation between their compositions when it comes to elements heavier than hydrogen and helium. This finding has important implications for our understanding of the planetary formation process.
