Saturn’s ‘Death Star’ Moon Is Unusual

By

Mimas, one of the many moons of the planet Saturn and nicknamed the “Death Star” moon because of its similarity in appearance to the fictional planet sized space station, appears to be what researchers call ‘wonky’ or filled with water.

It’s because Mimas wobbles. It’s wobble is twice as much as any moon its size and suggests something is under the surface like water or some other reason. The scientists studying the space body figure there’s either a massive ocean beneath its cratered surface or a rocky core that has such a weird shape as to explain the wobble.

This theory based on observation of this moon may well have astonishing results in planetary science. If there is a huge ocean beneath the surface of Mimas, is it water or some other liquid? Could life be inside? If it’s just a rocky core inside causing this moon to wobble, what configuration is it in? This might seem trivial to the public but the information could well explain and provide valuable data on many phenomena.

It’s theorized that several bodies in the solar system might have different cores and configurations. Some felt our moon was hollow and we sent satellites to crash into it to listen to the vibrations.

As more probes examine the various planets and moons and asteroids we’ll get a better picture of what is going on and that information should be used for further exploration of the cosmos.

NASA Discovered The Brightest Pulsating Dead Star

Space scientists have recently discovered a dead, pulsating star having brightest X-Ray emission through NuSTAR- Nuclear Spectroscopic Telescope Array. It seems that these emissions form from the energy of 1 million suns. The 9th of journal Nature reported the discovery for the first time.

This amazing discovery will help scientist to understand ULXs- ultra luminous X-ray sources. By now these ULXs are thought of as black holes having less mass and the recent data from Nuclear Spectroscopic Telescope Array decipher that galaxy M82- Messier 82 as a pulsar.

The NuSTAR principal investigator at the California Institute of Technology, Fiona Harrison in Pasadena said:

“You might think of this pulsar as the ‘Mighty Mouse’ of stellar remnants, it has all the power of a black hole, but with much less mass. The pulsar appears to be eating the equivalent of a black hole diet. This result will help us understand how black holes gorge and grow so quickly, which is an important event in the formation of galaxies and structures in the universe.”

Research is still going on to find out more about ULXs for more specific results. NASA also confirmed the emission of powerful X-rays from pulsar after observing the recent supernova through Chandra X-ray Observatory and Swift satellite.

Through NuStar, The scientists discovered the timings of the signal which enabled them to identify the pulse rate which was about 1.37 seconds along with energy output of 10 million suns which is almost ten times than the energy other pulsar emitting X-rays.

Scientists are still amazed of its brightness and they are still investigating reasons behind it .They are astonished by the fact that if it is eating up the matter around it, how it is doing so at such an extreme rate. They have decided to follow-up their research to find further details about the matter.
