First identified comet to visit our solar system from another star

Science Daily Astronomy - Thu, 2019-12-12 14:27
Comet 2I/Borisov is a mysterious visitor from the depths of space -- the first identified comet to arrive here from another star. Hubble images capture the comet streaking though our solar system and on its way back to interstellar space. It's only the second interstellar object known to have passed through the solar system.

Scientists map a planet's global wind patterns for the first time, and it's not Earth

Science Daily Astronomy - Thu, 2019-12-12 14:26
A new article documents the global wind patterns on any planet for the first time. Remote repogramming of the MAVEN spacecraft and its NGIMS instrument enabled the data collection. The results reveal seasonal stability in circulation patterns on Mars, but high short-term volatility in wind direction and speed. The data also allow researchers to infer the topography below based on waves created by the air mass flowing over features like mountains and canyons.

Newfound Martian aurora actually the most common; sheds light on Mars' changing climate

Science Daily Astronomy - Thu, 2019-12-12 10:58
A type of Martian aurora first identified by NASA's MAVEN spacecraft in 2016 is actually the most common form of aurora occurring on the Red Planet, according to new results from the mission. The aurora is known as a proton aurora and can help scientists track water loss from Mars' atmosphere.

Short-lived light sources discovered in the sky

Science Daily Astronomy - Thu, 2019-12-12 10:58
Roughly a hundred of very red, star-like sources that have appeared and vanished in short period of time have been discovered by a team of researchers when reviewing catalogue data, according to a new article. While most likely to be natural astrophysical sources the researchers are also taking extra-terrestrial sources into account.

Planet-mass objects in extragalactic systems

Science Daily Astronomy - Thu, 2019-12-12 09:59
A research group is reporting the detection of extragalactic planet-mass objects in a second and third galaxy beyond the Milky Way after the first detection in 2018. With the existing observational resources, it is impossible to directly detect planet-mass objects beyond the Milky Way and to measure its rogue planetary population.

ALMA spots most distant dusty galaxy hidden in plain sight

Science Daily Astronomy - Wed, 2019-12-11 12:19
Astronomers have spotted the light of a massive galaxy seen only 970 million years after the Big Bang. This galaxy, called MAMBO-9, is the most distant dusty star-forming galaxy that has ever been observed without the help of a gravitational lens.

Water common -- yet scarce -- in exoplanets

Science Daily Astronomy - Wed, 2019-12-11 08:26
The most extensive survey of atmospheric chemical compositions of exoplanets to date has revealed trends that challenge current theories of planet formation and has implications for the search for water in the solar system and beyond.

Stardust from red giants

Science Daily Astronomy - Tue, 2019-12-10 11:16
Some of the Earth's building material was stardust from red giants. Astronomers can also explain why the Earth contains more of this stardust than the asteroids or the planet Mars, which are farther from the sun.
