massive star explosion 30 million years ago detonation of 100 million suns
2016/5/6
A giant star that exploded 30 million years ago in a galaxy near Earth had a radius prior to going supernova that was 200 times larger than our sun, according to astrophysicists at Southern Methodist ...

2015/1/8
The Magellanic Clouds are the two brightest nearby satellite galaxies to our own Milky Way galaxy. From a new study it appears that not only are they much bigger than astronomers calculated, but also ...
The JCMT Nearby Galaxies Legacy Survey – V. The CO(J= 3–2) distribution and molecular outflow in NGC 4631
galaxy star
2014/12/20
We have made the first map of CO(J= 3–2) emission covering the disc of the edge-on galaxy, NGC 4631, which is known for its spectacular gaseous halo. The strongest emission, which we model with a Gaus...

Discovery Follow-up Nearby Galaxy Arecibo Zone Avoidance Survey
2011/10/13
The Arecibo L-Band Feed Array Zone of Avoidance (ALFA ZOA) Survey has discovered a nearby galaxy, ALFA ZOA J1952+1428, at a heliocentric velocity of +279 km s-1. The galaxy was discovered at low Galac...

The ionization of the emission line gas in nearby powerful radio galaxies。
Using the data from the Gliese-Jahreiss Catalogue and a particular
form of the galactic potential the authors construct galactocentric orbits for nearby
stars. The potential used in our paper is sta...

We present the results of a search for new candidate radio su-
pernova remnants (SNRs) in the nearby starburst irregular galaxies NGC 4214
and NGC 4395 using archived radio observations made with th...
April 25, 2007，A giant red orb in the sky shines down on planet Gliese 581c during the day, and at night the bright lights of two neighboring planets move gently through the starry skies. On the surfa...
