Astronomers find the nearest known blackhole to earth.

-
Astronomers have discovered a blackhole closer to earth than any found before. Located about 1,000 light years away in the southern constellation Telescopium, the blackholeweighs in at some four times the mass of our sun, which means it is only 7.5 miles wide.







Researchers found the blackhole while tracking binary stars using telescope at the latest silla observatory in Chile. When they take a closer look at the star system HR 6819, they noted that the inner star orbits quickly while the outer star orbits slowly along.



This meant the star are not just circling each other, some unseen third object has to be located near the center. The hidden object and the inner star dance around each other every 40 days. Meanwhile, astronomers says the invisible object is at least four times the mass of the sun, so it can only be a blackhole.




Finding a quiet blackhole that is not actively devouring a neighbor is dkffivdif because blackhole try not to betray themselves, but even without emitting light themselves, the gravitational effect blackholes have on other visible object can be very revealing for example, you can see the two stars orbiting the blackhole in HR 6819 with naked eye in the southern hemisphere.

    Could this be the gravitational nexus as to why the Earth isn't terribly bombarded with extra-terrestrial space bodies???

      Please elaborate your question more sir.

      I don't get that
      Make it more clear sir

The gigantic hole in the Arctic ozone layer is now closed

In this picture we can see that the large hole  in ozone layer is located on top of the northern part of earth. Fortunately, after one month the hole were closed and the main reason for the closing gap is the positive outcome of the Corona virus pandemic. The pollution level were way too high before, and now, when all the people are in lockdown, there is no traffic, no pollution and earth is repairing itself. These are how the Arctic hole looks like before it shrinks in April. One month later, on April 26 the image below show something fascinating and different. The hole is closed completely, scientists said we hach been making some remarkable positive impact in the last couple of decades.  The Montreal protocol in 1987 has set out goals, that scientists are following to lower human-made chemicals that are damaging the ozone layer. As a result of that, the enormous hole in the arctic is shrinking. Copernicus ECMWF shared on t

Despite the closure of earth's best telescope, the hunt for asteroids still continues

As the COVID-19 crisis continues around the planet, humanity’s gaze is firmly fixed on the pandemic playing out around us. Meanwhile, more than 100 of Earth’s largest research telescopes have been forced to shutter their doors, Astronomy magazine reported this week. It’s the perfect time for an asteroid to strike, many space fans deadpanned in reply. But there’s no need to worry about an incoming asteroid — at least, not any more than usual. Despite the closures, Earth’s top asteroid-hunting instruments remain on the prowl for potentially deadly space rocks. NASA funds most major asteroid-hunting efforts. The space agency has a congressional mandate to find some 90 percent of near-Earth objects (NEOs) larger than 460 feet (140 meters) across. As the name implies, NEOs are comets and asteroids that get a little too close for comfort. Asteroids offer clues to the early solar system and the promise of precious resources. That is, assuming they don’t kill us first. To learn mor

Satellites and telescopes took a deep look into Jupiter's atmosphere

A team of researchers led by Michael Wong at the University of California, Berkeley and including Amy Simeon of NASA Goddard space flights center in Maryland, and imkede Peter of UC Berkeley are combining multiwavelenghth observation from hubble and gemini with close up views from Juno orbit. Radio light show Jupiter's constant storm are gigantic compared to Earth's, with thunderheads reaching 40 miles from base to top five times taller than typical thunderheads on earth and powerful lighting flashes up to three times more energetic than earth largest bolts. Like lightning on earth, Jupiter lightning bolts act like radio transmitters, sending out radio waves as well as visible light when they flash across the sky. Evert 53 days, Juno races low over the storm systems detecting radio signals known as sperics and whistlers, which can then be used to map lightning even on the dayside of the planet or from deep clouds where flashes are not otherwise visibl
