NASA has planned to build a Starshade to look for Alien Planets. Starshade exoplanet-hunting missions may be technologically daunting.
The hottest place in the Universe was found some years ago. The cosmic hotspot was discovered by an X-ray telescope board a Japanese satellite called Suzaku. The cluster of galaxies, labelled RXJ1347, is five million light-years wide. So the hottest place in the Universe is situated in the constellation of Virgo.
Scientists combined their results with X-ray images taken by NASA’s Chandra space telescope to disclose that the record-breaking gas is contained within an area 450,000 light-years wide that is shining like a spot light.
In fact, the cloud’s temperatures reach a staggering 540 million degrees Fahrenheit (300 million Celsius)!
Virgo is one of the constellations of the zodiac. Its name is Latin for virgin. Lying between Leo to the west and Libra to the east, it is the second-largest constellation in the sky (after Hydra) and the largest constellation in the zodiac. It can be easily found through its brightest star, Spica.
In Greek mythology, Virgo is often identified as Dike, goddess of justice, who was the daughter of Zeus and Themis. She is often depicted holding the scales of justice, represented by the neighboring constellation Libra.
According to astronimate.com “Currently, astronomers are unsure exactly why this region is so hot. However, it’s likely that this galaxy cluster has seen multiple collisions with other clusters. Zooming through space at 2,500 miles per second, massive galaxy collisions are a recipe for true chaos. In fact, Tokyo University of Science professor, Naomi Ota claims galaxy cluster collisions produce the highest energy since the big bang”.
