Well, much as we’d like to share with you news about NUSAS and astronomy, there’s something we call “exams” that we have to worry about. Don’t worry, once it’s done (by about 10 May) we’ll be back with more updates.. Meanwhile, thanks for coming by! :)new balance outlet


The First Type-Y Star?

Contributed by: Huang Yunle
The spectral types of stars run from blue (hot) to red (cold): O B A F G K M. The discovery of brown dwarfs in the year 1995 extended the red ends with two newer cooler spectral types: L and T. The discovery of the CFBDS 0059 further extends the red ends to an even cooler spectral type: Y. It is the first sub-red brown dwarf that is cool enough to show ammonia in its spectrum. Read this article to learn more the spectral types of stars and the new discovery: CFBDS 0095.air max sneaker


Astronomers Find Suspected Medium-Size Black Hole in Omega Centauri

Contributed by: Huang Yunle
Omega Centauri is one of largest and most massive globular star clusters orbiting our Milky Way Galaxy. Observing this star cluster has showed that the stars are bunching up near its core. Measurements of the speed of the stars swirling near the cluster’s center revealed that the stars closer to the core are moving faster than the stars farther away, implying that some “unseen matter at the core is tugging on stars near it”. The most likely cause for this would be the presence of a medium sized black hole at the core of this star cluster.cheap air jordan


NASA Scientists Identify Smallest Known Black Hole

Contributed by: Huang Yunle
The new record holder- XTE J1650 is located in the center of a dying star. It is formed as a result of the collapse of the core of the star as it ran out of fuel for energy production. Not only identified as the smallest black hole, it is also the lightest known black hole, 3.8 times the weight of our sun.new balance outlet
