Search for Elusive Missing Link Black Holes Continues as Omega Centauri Observation Turns Out to Be a Dud

Published by Webster

A black hole once believed to bridge the gap between stellar-mass and supermassive black holes has been re-evaluated. The object, previously identified as an intermediate-mass black hole in the dense star cluster Omega Centauri, has been reclassified as a cluster of smaller stellar-mass black holes. This finding challenges earlier conclusions about the discovery of this elusive category of black holes. Omega Centauri, located within the Milky Way and containing around 10 million stars, has long been studied for its unique characteristics and potential remnants of a cannibalised dwarf galaxy. Analysis of Omega Centauri According to researchers, as reported by Live Science, the identification was based on unusual stellar velocities within Omega Centauri’s core. These movements were initially attributed to an intermediate-mass black hole, estimated at 8,200 solar masses, observed using the Hubble Space Telescope. The new study, however, factored in pulsar data, leading to the revised conclusion. Pulsars, rapidly rotating neutron stars emitting radiation beams, provided detailed insights into the cluster’s gravitational forces. Justin Read, a researcher at the University of Surrey, has stated to …

ISRO and NASA to Launch NISAR Satellite in March 2025 for Earth Observation

ISRO and NASA to Launch NISAR Satellite in March 2025 for Earth Observation

Published by Webster

American space agency NASA and the Indian Space Research Organisation (ISRO) are scheduled to launch the NASA-ISRO Synthetic Aperture Radar (NISAR) satellite in March 2025, as per multiple reports. The mission, estimated at Rs. 5,000 crore, aims to advance Earth observation capabilities globally. Reports indicate that the satellite, weighing 2.8 tonnes, will track planetary changes with precision and will scan nearly all of Earth’s land and ice surfaces every 12 days. Its dual-frequency radar technology is expected to deliver unprecedented data accuracy. Mission Features Advanced Radar Technology The NISAR satellite incorporates synthetic aperture radar (SAR) technology, enabling it to capture high-resolution images regardless of weather conditions or lighting. According to the official blog of NASA, its radar can detect surface changes as small as one inch and penetrate dense vegetation, making it a vital tool for mapping ecosystems and monitoring land dynamics. The dual-frequency radar combines NASA’s L-band and ISRO’s S-band, offering enhanced precision in data collection. Launch and Operational Details As per reports, ISRO’s GSLV Mk-II rocket might carry the NISAR satellite into a …

“Little Bit Surprised”: Australia Coach’s Observation After India Dominate Day 2 Of 1st Test

“Little Bit Surprised”: Australia Coach’s Observation After India Dominate Day 2 Of 1st Test

Published by Webster

The home team bowlers did not put a foot wrong but the pitch “surprisingly” dried up quite quickly at the Optus stadium on the second day, eventually helping the Indian batters, reckons Australia head coach Andrew McDonald. India openers Yashasvi Jaiswal (90) and KL Rahul (62) frustrated the hosts with their dogged unbeaten 172-run stand that has put the game in firm control of the visitors, who now lead by 218 runs. While the wickets fell in heap on the opening day with as many as 17 batters getting out, only three Australian tail-enders were dismissed on the second day. “The surface looked considerably dry today. It dried out fairly quickly,” said McDonald during the post-day press conference. “We thought there may have been a little bit more there. So, I suppose if you want to say that we were a little bit surprised, yeah, there wasn’t as much seam movement or swing. “The bowlers were presenting the seam in a similar fashion to they were yesterday. So I think the conditions may …

New Delhi: The Indian Space Research Organisation (ISRO) is set to launch the European Union’s Proba 3 Sun Observation Mission in December, said Union minister of state (independent charge) for science & technology, Jitendra Singh, on Tuesday. Union minister Jitendra Singh (right) and Isro chairman S Somanath during the third Indian Space Conclave in Delhi on Tuesday. (X / Dr Jitendra Singh) “The European Union’s large orbiter Proba 3, which will observe the Sun, will go to space from Sriharikota in December. Space scientists from ISRO and the European Union are going to jointly observe the Sun’s atmosphere,” Singh said speaking at the third Indian Space Conclave, organised by the Indian Space Association (ISPA). The Proba-3 satellite, which arrived in Sriharikota this morning is designed to observe the Sun’s faint corona. This mission marks India’s third launch for the European Union, following support for the Proba-1 and Proba-2 satellites, but stands out due to its focus on solar observation. The satellite will be launched by the PSLV-XL rocket. Singh noted that Proba-3 will offer important …

Moon to eclipse Saturn next week; here’s how you can watch | Pune News

On the night of October 14, the Moon will come directly between the Earth and the ringed planet Saturn, Arvind Paranjpye, Director, Nehru Planetarium, Nehru Centre said on Friday. “This occultation of Saturn by the Moon will be visible from India. It can be seen with the naked eye, but a pair of binoculars or a small telescope will be most helpful. If you have a good telescope, the event will be most enjoyable. The event will take place about half an hour after midnight on October 14,” Paranjpye said in a statement issued on Friday. In astronomical terminology, occultation occurs when one astronomical object hides the other. One is advised to observe the Moon and Saturn from about 11.30 pm on October 14. Saturn will be to the East of the Moon. As time progresses, the separation between the two will be seen reducing. Then, at some point, Saturn will start disappearing behind the Moon. After about an hour, Saturn can be seen coming out from behind the Moon. Click here to join Express …

NASA’s Hubble and New Horizons Collaborate for Uranus Observation, Shedding Light on Exoplanet Imaging

NASA’s Hubble and New Horizons Collaborate for Uranus Observation, Shedding Light on Exoplanet Imaging

Published by Webster

NASA’s Hubble Space Telescope and New Horizons spacecraft have joined forces to observe Uranus, a planet known for its mysterious atmosphere. Hubble, from its position in low-Earth orbit, captured detailed images of Uranus‘ atmosphere, including clouds and storms, while New Horizons, located 6.5 billion miles away, observed the planet as a small dot. These combined observations offer astronomers important insights into imaging distant exoplanets around other stars, providing essential context for future missions. A Unique Perspective on Exoplanet Imaging Lead author Samantha Hasler from the Massachusetts Institute of Technology, who works with the New Horizons team, explained that the collaboration between these two spacecrafts serves as a test case for observing distant exoplanets. Hubble’s close-up view of Uranus, in combination with New Horizons’ distant observation, helps researchers learn how gas giants similar to Uranus might appear when observed from light-years away. Valuable Insights for Future Missions The observations revealed that Uranus was dimmer than predicted in New Horizons’ data, providing a new understanding of how light is reflected at different angles. This discovery has significant …

How Pune Porsche Teen Went From Essay Writing To Observation Home In 3 Days

The Pune Porsche crash late on Saturday night left two 24-year-old engineers dead Pune: Fifteen hours after a late-night Porsche dash in Pune left two 24-year-old software engineers dead, the 17-year-old at the wheels was at his home, thanks to a bail order with conditions that were widely seen as appallingly flimsy. Three days later, he is at a child observation home, waiting for a decision on whether he will be tried as an adult, and his father in jail. On Sunday, hours after the chilling accident, the Juvenile Justice Board had granted bail to the teen, who was caught drinking on camera shortly before he drove the high-end car at over 240 km per hour, with a set of conditions. The conditions included writing a 300-word essay on “road accident and their solution”, studying traffic rules for 15 days and attending counselling for his drinking habit and psychiatric treatment. News of the bail and its conditions sparked massive outrage on social media, with many alleging that the teenager, son of a prominent Pune realtor, …
