Brecher's image captured spectacular detail in the sweeping spiral arms of the 260,000  light-year -wide galaxy gleaming with the intense light of star formation. Dense dust lanes can be seen coiling around  Andromeda's glowing galactic center , which is thought to house a supermassive black hole  140 million times  more massive than our sun. The nearby satellite galaxy M32 can also be seen as a bright ball on the upper edge of Andromeda's disk while the milky splash of light below is in fact the elliptical galaxy  Messier 110 , which plays host to around 10 billion stars of its o...

Credit: NASA/JPL-Caltech NASA  announced Wednesday  that its Perseverance rover discovered what scientists are calling a “potential biosignature” in a rock on Mars last year. This signature, which may have a biological origin but requires further study, represents the most compelling evidence to date for ancient microbial life on Mars, scientists and agency officials said in a press conference. The findings, detailed in a peer-reviewed  paper  published in the journal  Nature , center on a unique, leopard-spotted rock named Cheyava Falls, found within the ancient Jezero Crater that Perseverance has been exploring since 2021. The rock contains a cocktail of organic molecules and minerals strongly associated with biological...

This lunar eclipse is significant because over seventy-seven percent (77%) of the world's population will be able to see it. If you are in Asia, Australia, Africa, or Europe, you will have the opportunity to witness this eclipse. According to the provided map, the countries highlighted in red and black will experience a total lunar eclipse. Residents in these areas will be able to view every phase of the eclipse from beginning to end. Since Sri Lanka is located within this range, it will also have a clear view of the total lunar eclipse. The Saros number for this total lunar eclipse is 128, and its total d...

        From :-  Sky & Telescope By :- Bob King Editted by : - Amal Udawatta     On August 12, 2019, under a waxing gibbous Moon, a Perseid earthgrazer (left of center) scratches a path in the sky above Tucson, Arizona. Eliot Herman Aristotle postulated that meteors occurred when dry and smoky exhalations rose from cracks in the ground and ascended into the sublunar realm, where they suddenly burst into flame. The reality is much more exciting. Sand-sized grains spalled from 4.5-billion-year-old interplanetary travelers strike Earth's atmosphere at tens of thousands of kilometers per hour, fast enough to heat them to incandescence and etch the heavens with fleeting streaks of glowing air. Every year, around mid-August, Earth crosses the orbit of 109P/Swift-Tuttle. Debris from the comet strikes Earth's atmosphere, producing a meteor shower. Occasionally, our planet cuts across narrow, denser filaments laid down by the comet. This year, we expect a p...
