Several flares errupted from the Sun's corona

From Sky & Telescope, Edited by -Amal Udawatta, Several flares errupted from the Sun's corona on May 22nd. This image was captured in a series of 30 videos, compiled, and processed together. Jakob Andersen developed this image in May of this year from the Island of Falster, Denmark. The videos were taken through a TS Optics 480-mm Triplet APO refractor with a 2.7x Barlow lens, a Daystar Instruments QUARK hydrogen-alpha filter, and a ZWO ASI174MM camera. #astrophotography #solarflare #skyandtelescope

The largest species of moth in the world

  From - Earth Unreal , Edited by -Vinuri Randula Silva, Giant wood moths (Endoxyla cinereus) are the largest species of moth in the world. When fully grown, the females, which are around twice the size of the males, can weigh up to 1 ounce (30 grams) and reach a wingspan of 10 inches (25 centimeters), according to the Australian Museum. They live in forests across Australia and New Zealand QuestaGame/iNaturalist

Astronomers have found a dormant black hole orbiting a massive blue star in the Large Magellanic Cloud

From - Sky & Telescope, Edited by Amal Udawatta, This artist’s impression shows what the binary system VFTS 243 might look like if we were observing it up close. The system, which is located in the Tarantula Nebula in the Large Magellanic Cloud, is composed of a hot, blue star with 25 times the Sun’s mass and a black hole, which is at least nine times the mass of the Sun. The sizes of the two binary components are not to scale: in reality, the blue star is about 200 000 times larger than the black hole.  Note that the 'lensing' effect around the black hole is shown for illustration purposes only, to make this dark object more noticeable in the image. The inclination of the system means that, when looking at it from Earth, we cannot observe the black hole eclipsing the star. ESO / L. Calçada   An international team of astronomers is claiming the first unambiguous detection of a dormant black hole beyond our own galaxy. It seems to have formed without an accompanying supernov

China rocket: Uncontrolled return to Earth raises concern

  By Ella Hambly, BBC News, Edited by Amal Udawatta IMAGE SOURCE, GETTY IMAGES Image caption, The rocket lifting off from southern China on July 24, 2022 Debris from a Chinese rocket is expected to crash to Earth in an uncontrolled re-entry this weekend. The probability of it landing in any populated area is extremely low. But it has raised questions about how different countries take responsibility for their space junk. There have previously been  calls by Nasa  for the Chinese space agency to design their rockets to disintegrate into smaller pieces upon re-entry, as is the international norm. Recent rockets heading to China's unfinished space station, known as  Tiangong , have lacked the capability for a controlled re-entry. China space station: What is the Tiangong?

From Earth Unreal, Edited by Vinuri Randula Silva, photographed in the Guatemalan highlands. The Wine-throated hummingbird (Selasphorus ellioti) is a tiny hummingbird (bumblebee-sized), occurring in El Salvador, Guatemala, Honduras, and Mexico and inhabiting montane landscapes at elevations of 1500 to 3500m (4,900 and 11,500 ft). Males are more conspicuous, with the magenta-pink patch over their throat area. Their short tail have a rusty base and white corners on the tail tips.

Obituary: Bernard Cribbins

  Edited by - Vinuri Randula Silva IMAGE SOURCE, GETTY IMAGES Bernard Cribbins was a multi-talented performer. Actor, comedian, singer and raconteur: he had a go at everything from Shakespeare to pantomime, Jackanory to Top of the Pops. He was the voice of the Wombles, Catherine Tate's cuddly grandpa in Doctor Who, and the irate-but-soft-hearted station master who tugged at our heartstrings in 1970 film The Railway Children. When he was nearly 90, he published an autobiography looking back on his years in show business in 2018. Its title was Bernard Who? 75 Years Of Doing Absolutely Everything - and its advice was simple. "Do your best and be grateful for every single job". Two lines and a smile Bernard Cribbins was born into a working-class family in Oldham, Lancashire on 29 December 1928. These were harder times. Cribbins' mother worked barefoot in a local factory; his father was a champion "clog-fighter" - a method of settling disputes by kicking an oppon
