By studying white dwarf stars, and finding some of them, well, in a way polluted, astronomers have found that most rocky exoplanets are made of rocks we can’t find anywhere in our Solar System.
As galaxies in a cluster slam into each other and the surrounding matter, they create bow shocks, causing movement of the plasma around these clusters. With the maps provided by the high-energy jets coming out of black holes, the task can be a little easier.
Astronomers used the Atacama Large Millimeter/submillimeter Array or ALMA get a help from Natural Binocular to find a baby galaxy on a cosmic merry-go-round.
Just like the familiar maps we use to navigate our own neighborhoods and cities, astronomers develop maps of the galaxy too! Using the power of several telescopes across Japan, astronomers have teased out some new insights as to the precise location of the Earth within our Milky Way Galaxy.
In the accretion disc of AB Aurigae, astronomers observed a clear overall spiral structure with a little twist or a spiral kink in the accretion disc that marks the spot where a planet may be forming.
Collecting stuff is fun but it can also tell you something about the things you’re collecting. One of the collection are pictures of stars explosion.
The South Pole is a hostile environment; it’s a frozen desert but for the last 8 years, scientist try to look for this answers: What shoots beams of tiny, almost undetectable particles at Earth?
When a red supergiant goes supernova, something special may happen: a brief but brilliant flash of light might be seen before the full explosion! more at #365DaysOfAstro @unawe #spacescoop
When looked at with X-ray telescopes, they shone as bright as a million suns combined. #spacescoop @unawe at #365DaysOfAstro
