Sun’s surface is marked by electrically charged gases that keep generating powerful magnetic forces. Their area of influence is called magnetic fields. As these gases are dynamic, they continuously stretch and twist the magnetic fields. Sometimes, this tangling of magnetic fields causes a sudden explosion of energy called solar flares. These flares, if strong enough,

A recent research based on Hubble Space Telescope findings showed that black holes could go against their all-absorbing nature at times and may aid creation. The research showed a supermassive black hole at the centre of a dwarf galaxy, some 30 million light-years away, creating stars rather than swallowing it. The black hole is apparently
NASA said it has completed deploying all the hexagonal mirror segments of its James Webb Space Telescope. The delicate operation to move the $10-billion (roughly Rs. 74,500 crore) space observatory’s individual mirror segments out of their launch positions took nearly a week, during which the motors made over a million revolutions. The space agency said
Researchers on Thursday reported the latest in a surprising string of experiments in the quest to save human lives with organs from genetically modified pigs. This time around, surgeons in Alabama transplanted a pig’s kidneys into a brain-dead man — a step-by-step rehearsal for an operation they hope to try in living patients possibly later
Space Entertainment Enterprise (SEE) is planning to launch what it claims is the world’s first entertainment studio and multi-purpose arena in zero gravity. The company is co-producing Tom Cruise’s upcoming space movie. SEE has unveiled plans to build a space station module that contains a sports and entertainment arena as well as a content studio by
A Chinese satellite had a near collision with one of the many chunks of debris left by the fallout of a recent Russian anti-satellite missile test, state media reported. Moscow blew up one of its old satellites in November in a missile test that sparked international anger because of the space debris it scattered around
NASA said its Curiosity rover, looking for signs of life on Mars’ Gale Crater, has found intriguing carbon signatures. While this is no definite suggestion that Curiosity has found proof of ancient microbial life, it does, however, suggest its possibility. The rover has been collecting powdered rock samples on the Red Planet’s surface. When scientists
An asteroid bigger than the tallest building on Earth safely flew by on January 19. The giant rock, named 7482 (1994 PC1), zipped past our planet, nearly 1.93 million kilometres away. That’s more than five times the distance between Earth and Moon. It has been classified as “potentially hazardous” because of its size and its
ExoMars — a joint project of European Space Agency (ESA) and Russia’s Roscosmos — has moved a step closer to landing on the Red Planet after it rehearsed how to drive off its Kazachok landing platform on the Martian surface. The simulation involved the UK-built Rosalind Franklin rover making a carefully choreographed move on the
The race for space exploration is heating up with major powers focussing on having a base on the Moon, to help operate beyond the International Space Station (ISS). As the US is realigning its strategy to return humanity to the Moon, China is not far behind. Its scientists have created an “artificial moon” on Earth
Scientists have discovered more than 10,000 exoplanets, those that lay quietly beyond our solar system, but they have not been able to locate a moon orbiting any of them – so far. In a new study, they have outlined a discovery that they say could change this. Researchers think the celestial body they have now
Extra-terrestrial living comes with a number of complications, but astronauts tackle those all the time aboard the International Space Station (ISS) in their endeavour to solve the many mysteries of the Universe. And scientists back home keep trying to find ways to make living on the ISS easier. One of the biggest problems astronauts face
Volunteers interested in astronomy and curious about celestial objects have helped NASA find a super giant planet outside our solar system. This exoplanet is three times the size of Jupiter and located about 379 light-years away from Earth. The super-Jupiter orbits a star with the same mass as our Sun. NASA said this discovery was
A measuring system that measures the thermal conductivity of bridgmanite in the laboratory, under the pressure and temperature conditions that prevail inside the Earth, has been developed by a team of researchers. The study has been published in the ‘Earth and Planetary Science Letters Journal’. The evolution of our Earth is the story of its cooling: 4.5 billion years
Macro photography in its truest form deals with photographing minute things to make them appear larger than life, characteristics that the naked eye would often miss. That by itself can make things magical — making the mundane appear awesome! That flower you see from far as pretty can be pretty captivating up-close, with the anthers,
Joshua Martinangeli, 7, is too ill to go to school. But the German student can still interact with his teacher and classmates through an avatar robot that sits in class in his place and sends a blinking signal when he has something to say. “The children talk to him, laugh with him and sometimes even
An international team of scientists has produced the most detailed 3D map of the universe yet, with astrophysicists unveiling details of the first 7.5 million galaxies out of 35 million. The stunning image shows the cosmic web of galaxies going back billions of light-years. And, this is only the beginning of the project, which is
The dawn of humanity is a subject that has long intrigued us. Scientists have been trying to ascertain the precise date of origin for a long time but with little success. Every once in a while, they find fossils that push the date by a few more centuries. But the effort is still on. Scientists
As NASA completes all major deployments of the James Webb Space Telescope and the observatory enters a “cooling” period, the agency is sharing some interesting facts about the $10-billion (roughly Rs. 74,100 core) observatory. These include some lenses which are made out of salt. But why does this infrared telescope need a “salty” lens? In
A Virgin Orbit rocket released from a jet flying off the California coast carried seven small satellites into space on Thursday as the company kicked off a year in which it plans to ramp up the pace of launches, including two originating from Britain. Virgin Orbit’s modified Boeing 747 took off from Mojave Air &
In a recent experiment, scientists have taught a goldfish to operate a robotic car. The experiment was an attempt to test the navigational abilities of goldfish and study animal behaviour. The robotic car was specially designed to suit this purpose. The Fish Operated Vehicle (FOV), designed by scientists from Ben Gurion University of the Negev
NASA on Wednesday embarked on a months-long, painstaking process of bringing its newly launched James Webb Space Telescope into focus, a task due for completion in time for the revolutionary eye in the sky to begin peering into the cosmos by early summer. Mission control engineers at NASA’s Goddard Space Flight Center in Greenbelt, Maryland,
Using NASA’s Chandra X-ray Observatory, researchers have identified a black hole having 200,000 times the mass of the Sun in Mrk 462, a dwarf galaxy with only several hundred million stars. In comparison, our Milky Way has a few hundred billion stars. The black hole was heavily buried in gas and dust in Mrk 462
A 1 km-long asteroid is set to zip past Earth next week. But there is no need to worry. The flyby will have a very safe clearance of 1.93 million km from Earth, meaning it would be more than 5.15 times farther away from us than the Moon. Scientists and astronomers keep a regular watch
Our galaxy, the Milky Way, houses the Solar System and its varied mysteries. But there are hundreds of galaxies like ours in the cosmos and all of them are hiding multiple enigmas. They arouse acute interest among scientists, who are drawn towards them because of these puzzles. One of the most interesting puzzles is how galaxies
China’s Chang’e 5 lunar lander has found the first-ever on-site evidence of water on the surface of the moon, lending new evidence to the dryness of the satellite. The study published on Saturday in the peer-reviewed journal Science Advances revealed that the lunar soil at the landing site contains less than 120 parts-per-million (ppm) water or
NASA’s new space telescope opened its huge, gold-plated, flower-shaped mirror Saturday, the final step in the observatory’s dramatic unfurling. The last portion of the 21-foot (6.5-meter) mirror swung into place at flight controllers’ command, completing the unfolding of the James Webb Space Telescope. #NASAWebb is fully deployed! ???? With the successful deployment & latching of
NASA has shared an image of a stunning cosmic duo of galaxies, located roughly 215 million light-years away from Earth in the Pisces constellation. The image was clicked by the Hubble telescope, NASA’s current workhorse to study the mysteries of deep space. NASA said the galaxies appear to be plunging into each other, but in
NASA’s Mars rover Perseverance is in the process of collecting rock samples to send back to Earth via a future human mission to Mars. But some pebble-sized debris is creating problems for the machine. At first, things went smoothly. Perseverance successfully extracted a sample from a Martian rock, named Issole. However, while transferring the sample
“Space now,” was what Japanese billionaire Yusaku Maezawa wanted to tweet for years. He finally really did it, from the International Space Station. “The space market holds so much potential,” he said Friday at the Foreign Correspondents’ Club in Tokyo, his first news conference in Japan after returning to earth before Christmas. Maezawa, who heads
We have often heard and read about giant stars dying violently in deep space. Ever imagined what kind of a sight it would be? How would a star appear as it nears its end from Earth? We may finally have an answer. In a first for astronomy, researchers were able to see in real time
Through the past week, NASA engineers have been working diligently to deploy major equipment and tools aboard James Webb Space Telescope (JWST), including its sunshield and secondary mirror. On Saturday, January 8, the primary camera of the $10-billion (roughly Rs. 74,340 crore) space observatory will be deployed, which will study the origin of the Universe
James Webb Space Telescope, a day after fully tensioning the sunshield, has now completed another complex procedure. The space observatory’s secondary mirror was deployed using what a Webb engineer described as the “world’s most sophisticated tripod.” The 2.4-feet-wide mirror is located on the tips of three carbon fibre tubes which extend out from the large
