Just when you would think that 2019 is over for Astronomy, right during its last days, we receive even another outstanding news about our Cosmos. Since the Observable Universe is tens of billions of light-years across, we can only expect it to keep providing us surprise after surprise.
The latest big hit is NASA’s announcement that a tremendous collision is awaiting, like no-other ever seen before. Two galaxy clusters are expecting to collide at some point in the future, and they are approaching extremely fast.
4 million mph is the speed of the clusters
The researchers involved have been using NASA’s Chandra X-ray Observatory, ESA’s XMM-Newton, the Giant Metrewave Radio Telescope (GMRT), and some optical observations. Thus, they concluded that the two galaxy clusters are approaching each other at staggering speeds: 4 million miles per hour. Also, NASA claims that the collision foreseen could be the most violent one between two clusters of galaxies.
The scientists have been using their advanced tools to look very deep into space in order to find the clusters: 380 million light-years away from Earth.
20 million Degrees Celsius
The heat leftover by the clusters hurtling through space can make ‘jealous’ even the one produced at the Sun’s surface. 20 million Degrees Celsius is the maximum temperature of the two galaxy clusters.
NASA playfully said in a statement, proving that the guys working there are also having a sense of humor:
As the holiday season approaches, people in the northern hemisphere will gather indoors to stay warm.
In keeping with the season, astronomers have studied two groups of galaxies that are rushing together and producing their own warmth.
The researchers estimate that the total mass contained in NGC 6338 is about 100 trillion times the mass of the Sun.
The notorious American space agency also published a photo of the two clusters hurtling towards each other, and they look beautiful:
We cannot help to ask ourselves what amazing beauties will Astronomy reveal to us in 2020. Is anybody willing to bet on aliens?
