[ad_1] NASA said Monday it was looking for ways to bring Martian rocks collected by the Perseverance rover back to Earth earlier and at a lower cost than planned after facing criticism for going massively over budget. HT Image The effort comes as China is making progress towards a simpler “grab-and-go” sample return mission to the red planet “around 2030,” according to state media, which would make it the…

[ad_1] NEW DELHI: With spring’s arrival in the Northern Hemisphere, parts of Asia are once again grappling with the annual menace of dust storms, which have recently shrouded regions like China’s Inner Mongolia in a thick yellow haze. On March 27, 2024, residents of Erenhot, Inner Mongolia, witnessed their skies turn murky, with state media advising people to stay indoors as winds whipped up dust with speeds reaching 100…

[ad_1] NEW DELHI: The James Webb Space Telescope (JWST) has made a groundbreaking discovery, identifying the source of the most potent cosmic explosion since the Big Bang, known as “the BOAT” or “brightest of all time.” This gamma-ray burst (GRB), which sent highly energetic photons towards Earth, was first detected by ground and orbital telescopes on October 9, 2022, originating from 2.4 billion light-years away in the constellation Sagitta.A…

[ad_1] Over millennia, mighty geological processes in the earth’s crust heated and compressed together pieces of life-forms that had been dead for a while. Eventually, this mulch of organic matter accumulated as hydrocarbons inside rock formations. The two Industrial Revolutions were the result mainly of people finding a way to extract these hydrocarbons and using them to drive many and great engines, whose foul breath polluted the air and…

[ad_1] NEW DELHI: Nasa is tackling one of the biggest challenges of lunar and Martian exploration: pervasive and abrasive dust. With the Moon’s surface covered in a jagged, glassy material known as regolith, and Martian dust threatening to coat everything from solar panels to spacesuits, these tiny particles pose a significant risk to equipment and astronaut health.To address these issues, Nasa researchers are developing an innovative electrodynamic dust shield…

[ad_1] The National Aeronautics and Space Administration’s (NASA) James Webb Space Telescope (JWST) has captured an image showing red glowing gas and dust being cast out from the center of a starburst galaxy known as the Cigar Galaxy. The Cigar Galaxy, also known as Messier 82 (M82), has a compact but turbulent environment at its core, which can provide scientists a clearer picture of how stars are born en…

[ad_1] Unlike actual gold, hydrogen is spectacularly useful. As a fuel, in theory, it could power cars, buses, planes and ships. It could be burned in power plants, generating electricity. And because, unlike fossil fuels, it emits no greenhouse gases, it could help curb climate change (so long as it is cleanly obtained). Governments are throwing subsidies at efforts to make hydrogen fuel. America’s Inflation Reduction Act offers lavish…

[ad_1] A big open problem in cosmology is the Hubble tension. There are two equally valid ways to measure how fast the universe is expanding, but they have yielded two very different estimates. No amount of rechecking and refining calculations has made this tension go away. In a study published recently in Monthly Notices of The Royal Astronomical Society (MNRAS), scientists from Germany and the U.K. led with a…

[ad_1] The National Aeronautics and Space Administration (NASA) is preparing the Europa Clipper spacecraft for a mega launch in October this year. It is the “largest spacecraft NASA has ever built for a planetary mission,” NASA’s Jet Propulsion Laboratory JPL said in a post on X earlier this week. Here are Top 5 key facts you need to know about the Jupiter-bound Europa Clipper spacecraft. Watch videos for details:…

[ad_1] Jupiter is the largest planet in the solar system, but the focus of astronomers has not been that much on this gas giant as on other planets like Mars. The reason is simple – the Red Planet is considered as the best option for humanity to colonise another planet. Jupiter definitely is not on that list, as yet, but its moon Europa may well be one day. NASA’s…

However, while most of these types of clusters are home…

[ad_1] NEW DELHI: People relying on willpower to resist temptations and achieve goals are perceived as more trustworthy compared to those resorting to “commitment strategies” such as using apps, a new research has shown. In one experiment, participants were found to judge hypothetical users of commitment strategies as less trustworthy despite recognising that sometimes these strategies are more effective than willpower alone, researchers said. Approaches involving commitment strategies have…
