Celestial visitor: a new “mega comet” has taken off in our solar system!
From mysterious interstellar objects like the ‘Oumuamua, to several not-so-unique space rocks, a plethora of celestial objects constantly visit our celestial backyard that is the solar system. Now one of these remarkable objects has been spotted on the far reaches of our solar system, only this one appears to be a much larger comet than the typical comets we are used to! More details on this mega comet here.
Star Explosion’s Blast Wave creates a cosmic “hand”; Chandra X-ray observatory measures its movement
From a jellyfish floating in space to the beating of bat wings – some very complex phenomena occurring very far in the observable universe, sometimes end up looking like simple actions and beings we know so well in our life here on Earth. Now one of those parallels has reappeared from the depths of our own Milky Way galaxy, in the form of a shapely hand! Read all about it here!
NASA’s James Webb Telescope to Help Us “Time Travel” in the Early Universe, Solve Mysteries by Looking into Quasars
When we look at the sky and see the twinkling stars, we see the stars as they would have been tens to hundreds of years ago, because the light from these distant celestial bodies takes years to reach our planet. But soon our ability to look back and look deeper into the universe will be dramatically amplified, thanks to NASA’s James Webb Space Telescope, which will use quasars to unlock the secrets of a very young universe.

#SpaceTrends: Glimpses of Strawberry Moon from various parts of the globe (PHOTOS)
During the midnight hours of June 25, the night sky was adorned with the majestic beauty of the full moon. This particular full moon, however, has been recognized with the special name of Strawberry Moon around the world. Check out photos of this celestial event from around the world, here.
Orbiting the Moon, Chandrayaan-2 observes the Sun to help understand the mysterious warming of its crown
The Chandrayaan-2 orbiter, which continues to orbit the Moon and complete its missions, is also monitoring the Sun at the same time! Now he has amassed crucial data using one of his instruments, the Solar X-Ray Monitor. Using this information, Indian scientists have unraveled the long-standing mystery behind the ultra-hot corona, the outermost part of the Sun’s atmosphere. Read all about it here.
Tectonic movements on Venus suggest hell planet may still be geologically alive
Venus, the “lost habitable” world of our solar system, is now considered a dead planet surrounded by a highly toxic environment. But following the detection of phosphine on its clouds in 2020, astronomers turned to our neighboring world, which led to the unearth of mysterious but fascinating phenomena. Now, a new study has highlighted evidence of tectonic movement occurring on the surface of Venus, suggesting the planet may still be geologically active! Read on here.
Following the Painted Lady’s Trail: 22-year study explains longest insect migration route
The ‘Painted lady butterflies’ are true cosmopolitans! Known to undertake extremely long migrations, these tiny insects fly cooler north in summer and warmer south in winter. Today, in a 22-year collaborative study, researchers have successfully tracked their journey, which is the longest insect migration route known today! More details here.

Lost ancestors: Discovery of unknown species of ancient humans in Israel promises to unravel long-standing mysteries
For hundreds of thousands of years, several archaic species of humans inhabited Earth simultaneously. The most popular and perhaps the closest ancestors to us are the recently discovered Neanderthals and Denisovans. But now a team of Israeli scientists have unearthed startling evidence that sheds light on a whole new type of Homo species unknown to science. Full story here.
The Earth has a pulse that beats every 27 million years! Each could lead to planet-altering transformations, scientists say
About 4.5 billion years ago, after a great battle between swirling gas and dust, planet Earth was formed. Since then, it has undergone geological processes that have led to planetary transformations, from the division of continents to massive extinctions. But did these changes happen at random? Or did they follow an established pattern? A new study has shed light on the planet’s geological activity, indicating that a massive cycle could be at play. Read here.
Giant rhino that roamed parts of Asia 26.5 million years ago discovered in China
Every now and then scientists come across fossils belonging to a whole new set of fascinating creatures. A new find like this has now unraveled one of those giant species of land animals that roamed parts of Asia. The animal has been identified as a giant rhino, one of the largest of its kind ever to be discovered! Read all about it here.
