Milky Way and Andromeda Galaxies Have the Same Mass
In 2012, NASA astronomers predicted that our Milky Way galaxy will collide and merge with its neighboring Andromeda galaxy in about 4 billion years. Scientists said that when this galactic collision takes place, Andromeda, which was thought to be two to three times the size of the Milky Way – will completely engulf our galaxy. Now, […]
Jupiter’s Northern Lights; Watching Stars Explode & Too Much Sitting Kills
Astronomers Study Jupiter’s ‘Northern Lights’ Earth’s Auroras – Borealis in the northern polar region and Australis in the south – are among the most beautiful and haunting light displays in nature. Now, for the first time, scientists have been able to study Jupiter’s auroras, in x-ray wavelengths thanks to NASA’s Chandra X-Ray Observatory. Auroras both […]
Astronomers Find a Bunch of ‘Monster Stars’ in Star Cluster
A group of astronomers probing a young star cluster within the ultraviolet section of the light spectrum just found a bunch of huge ‘monster stars.’ The R136 star cluster, located in the Tarantula Nebula, inside the Large Magellanic Cloud, is about 157,000 light years from Earth. They chose to explore in the ultraviolet range since there are […]
Rhythmic Light Pulses Help Astronomers Accurately Measure Medium Sized Black Hole
Astronomers have calculated that there may be about 100 million black holes in the galaxy. And they mostly fall into two sizes… stellar and supermassive. The size difference has to do with how much mass they contain versus that of our own sun or solar mass. For some time now, astronomers have also theorized that […]
