Astronomers have discovered the smallest black hole ever to exist in the history of the universe. The black hole could help scientists better understand how massive stars explode, which ones leave behind black holes or neutron stars, and the number of black holes in our galaxy and others. The...
The Milky Way's bright satellites as an apparent failure of ΛCDM We use the Aquarius simulations to show that the most massive subhaloes in galaxy-mass dark matter (DM) haloes in cold dark matter (CDM) are grossly incon... Michael Boylan‐Kolchin,JS Bullock,M Kaplinghat - 《Monthly Not...
And there is more. Not only is this pulsar the youngest of the 3000 known in ourMilky Waygalaxy, but it also belongs to a very rare category of pulsars: magnetars, the cosmic objects with the strongest magnetic fields ever measured in the Universe. “Swift J1818.0-1607 lies around 15,000...
Scientists have announced the discovery of the youngest known exploding star, or supernova (超新星), in our Milky Way galaxy (银河系). Astronomers say the remnant (残骸) of the most recent supernova could provide clues to a long-standing mystery about why so few supernovae seem to explode...
In any case, Keli Quintela's time alone in the dark forced her to confront her own fears in a big way, something that every Lantern must do in order to truly serve and protect the galaxy with the light of willpower. Now, she's ready to venture forth and embrace her destiny as a...

As the light of the explosion reached the brightness of 2.5 billion suns, then slowly faded, the team worked backward to determine exactly when the supernova occurred. Located only 21 million light-years from Earth in the Pinwheel Galaxy, the supernova is the closest one to our planet in 25...
The young type-1a supernova was discovered in August. It is in the Pinwheel Galaxy -- about twenty-one million light years from Earth. A light-year is the distance light travels in one year – about ten trillion kilometers. That may sound like a great distance. But this galaxy is somew...
