NASA Solves The Andromeda X-Ray Mystery

NASA Solves The Andromeda X-Ray Mystery

Astronomers have finally discovered the cause behind the mysterious X-ray emission that was previously observed near the center of the Andromeda galaxy. It turns out that the high-energy emission is a pulsar – the incredibly dense core of a dead star left over by a supernova. This pulsar, known as Swift J0042.6+4112, is not a common one: It is…

Astronomers Released 3D Map Of The Milky Way's Dust

Astronomers Released 3D Map Of The Milky Way's Dust

If you do any housework, you probably hate dust. If you’re an astronomer, your relationship with dust might be a bit more ambivalent. If you want to learn about star and planet formation, then you love stardust. If you are trying to measure precisely how far away galaxies are, then dust is an annoyance. A…

Runaway Black Hole Might Have Been Propelled By Gravitational Waves

Runaway Black Hole Might Have Been Propelled By Gravitational Waves

The Hubble Space Telescope has detected a runaway supermassive black hole that they believe was kicked out from the galaxy core thanks to a huge directional emission of gravitational waves. The dramatic scene is taking place in galaxy 3C186, located 8 billion light-years away. Its supermassive black hole, which weighs 1 billion times our Sun, is surprisingly not…

The Ice of Ceres Tell Us About Its Changing Tilt

The Ice of Ceres Tell Us About Its Changing Tilt

Ceres might be the queen of the asteroid belt, but it’s a small fish compared to Jupiter and Saturn. These gas planets have been messing with the dwarf planet, changing its inclination over a short amount of time. According to the data collected by NASA’s Dawn, over the last 3 million years, Ceres’ tilt has ranged from…

Early Universe Galaxies Like Ours Are Surrounded By "Super Halos"

Early Universe Galaxies Like Ours Are Surrounded By "Super Halos"

With every generation of telescopes, we are getting a better idea of what the young universe looked like and the latest observation from the Atacama Large Millimeter/submillimeter Array (ALMA) has thrown quite a curve ball. By studying two early universe Milky Way-like galaxies, astronomers have discovered the progenitors of giant spiral galaxies were embedded in…

Citizen Scientists Bring Astronomical History To Light

Citizen Scientists Bring Astronomical History To Light

Pre-digital age journals are filled with old astronomical images. Sometimes they contain information precious to science, if only we could find them. Now everyone with an interest in astronomy, or a liking for archives, and some time on their hands can help. As with all citizen science projects, there’s the possibility of being part of…
