, is making a close approach to Earth, drawing global attention from scientists and space agencies. Though the flyby poses no threat, it offers a valuable opportunity to study how such near-Earth objects (NEOs) behave. With NASA confirming the asteroid's safe distance and trajectory, and ISRO expressing renewed interest in planetary defence strategies, the event highlights the importance of early detection and international cooperation. As space agencies track and prepare for future events like Apophis 2029, the flyby of 2025 MA90 reminds us that cosmic vigilance is essential.
NASA's asteroid 2025 MA90 to flyby today: Date, speed and distance
An asteroid nearly the size of a city building is heading toward Earth, sparking interest but not alarm among scientists. Known as asteroid 2025 MA90, this space rock is being closely monitored as it prepares for a safe flyby on July 15. Measuring approximately 280 feet across and traveling at an impressive 20,263 miles per hour, MA90 is expected to pass by Earth at a distance of about 4 million kilometers. Though the approach is relatively close in cosmic terms, NASA confirms there is no risk of impact. The event serves as a reminder of our planet's vulnerability—and our increasing readiness.
According to NASA, asteroid 2025 MA90 is classified as a member of the Aten group of asteroids—a class of near-Earth objects that orbit the Sun and sometimes cross Earth's orbit. However, this particular asteroid does not meet the criteria to be considered potentially hazardous. For an object to qualify as hazardous, it must be at least 85 meters wide and come within 7.4 million kilometers of Earth. While MA90 meets the size threshold, its projected flyby distance of approximately 4,020,000 kilometers places it safely outside the danger zone.

Why tracking close approaches of asteroids still matters
NASA's scientists continue to track the asteroid's trajectory for any changes, as even minor orbital shifts can affect long-term calculations. Nevertheless, this flyby offers a valuable opportunity for astronomers to study its movement, composition, and behavior in more detail using ground-based and radar observations. Though 2025 MA90 is not a threat, the incident reflects why tracking near-Earth objects (NEOs) is crucial for planetary defence. Even objects that miss Earth can reveal critical data about asteroid orbits, spin rates, and composition. These insights are vital for preparing for potential future threats.
NASA and other space agencies around the world maintain extensive monitoring systems to catalog thousands of such asteroids, identifying any that may warrant further observation or mitigation strategies. This proactive approach aims to ensure that humanity is never caught off guard by a surprise impact.
ISRO eyes Apophis 2029 and global planetary defence efforts
While the focus now is on MA90, India's space agency ISRO has its eyes on a much larger and more complex challenge—the anticipated 2029 flyby of asteroid Apophis. This massive near-Earth object, measuring over 1,200 feet in diameter, will pass alarmingly close to Earth, within a distance of about 32,000 kilometers—closer than many satellites.
ISRO Chairman S. Somanath has stressed the importance of collaborative global action to address such cosmic threats. He advocates for deeper cooperation between ISRO, NASA, ESA (European Space Agency), and JAXA (Japan Aerospace Exploration Agency). Together, these agencies can lead planetary defence missions that include impact deflection tests and potentially even asteroid landings. ISRO is reportedly developing missions that could involve landing on an asteroid, a bold step that would allow scientists to study their surfaces and structure directly.
Asteroid MA90 flyby underscores the urgency of global planetary defence
The peaceful flyby of asteroid 2025 MA90 should not overshadow the growing urgency in space science to build robust defence strategies. With the increasing detection of NEOs, the global community recognizes that Earth is not immune to cosmic hazards. Events like the Chelyabinsk meteor in 2013 have shown how even small asteroids can cause significant damage.
Thus, every close encounter becomes both a warning and a learning opportunity.

New worlds in the making: Is this how our solar system was born?
For the first time, astronomers have witnessed the very first solid particles forming around a baby sun-like star, HOPS-315, over 1,300 light-years away. Using Nasa's James Webb Telescope and ALMA in Chile, scientists captured the earliest stage of rocky planet formation — offering a rare, real-time glimpse into how planetary systems like our own begin to emerge read more The breakthrough was made possible with data from the Atacama Large Millimeter/submillimeter Array (ALMA), an array of 66 radio telescopes located in the desert of northern Chile, and observations from the James Webb Space Telescope (JWST). Representational Image/Pixabay Astronomers have, for the first time, directly observed the earliest physical conditions in which rocky planets begin to form around a distant, young star. The observations offer clarity into how planetary systems like our own are born — capturing the beginning of planet formation as it unfolds around a protostar known as HOPS-315, located approximately 1,300 to 1,370 light-years away in the Orion constellation. This celestial breakthrough was made possible through coordinated efforts by the James Webb Space Telescope (JWST) and the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile. STORY CONTINUES BELOW THIS AD By studying the gaseous and dusty disk around HOPS-315 — a sun-like star still in its infancy — researchers have conclusively identified the condensation of hot mineral grains: the initial building blocks from which planets eventually emerge. The genesis of the solar system HOPS-315 is a young, sun-like protostar believed to be between 100,000 and 200,000 years old, making it one of the youngest known stars to exhibit early planetary formation processes. At this stage, a star is typically surrounded by a thick envelope of gas and dust — residual material from the collapse of the interstellar cloud that birthed it. This structure, known as a protoplanetary disk, is the very environment in which future planets form. Using JWST's infrared capabilities and ALMA's powerful radio imaging, scientists managed to peer through a gap in the outer disk of HOPS-315. This opening, coupled with the favourable tilt of the star's disk toward Earth, allowed for a rare observational window into the hot inner region of the disk where solids begin to emerge. In this region, researchers detected crystalline silicate minerals and silicon monoxide gas — materials that also appear in meteorites on Earth and are considered among the first solids to have condensed in the early solar system. 'We've captured a direct glimpse of the hot region where rocky planets like Earth are born around young protostars,' AP quoted Melissa McClure of Leiden Observatory, who led the international team. STORY CONTINUES BELOW THIS AD 'For the first time, we can conclusively say that the first steps of planet formation are happening right now.' Echoes of our own solar system One of the most significant aspects of this discovery is the detection of silicon monoxide, both in its gaseous form and in crystalline structures. These materials condense only at extremely high temperatures and are thought to be the earliest solids to form in our own solar system over 4.5 billion years ago. 'Meteorites are fragments of asteroids that formed 4.6 billion years ago at the same time that the planets of our solar system were taking shape,' noted the research team. These ancient space rocks contain embedded crystalline minerals rich in silicon, offering scientists a sort of fossil record of solar system formation. Now, the observation of identical mineral signatures in the HOPS-315 disk supports the idea that these high-temperature condensation processes are not unique to our solar system. Instead, they may be a universal characteristic of planet formation around young stars. 'This process has never been seen before in a protoplanetary disk — or anywhere outside our solar system,' Space quoted Edwin Bergin, a member of the research team from the University of Michigan. STORY CONTINUES BELOW THIS AD The location of these minerals in the HOPS-315 system — at a distance from the star comparable to the main asteroid belt between Mars and Jupiter. 'We're really seeing these minerals at the same location in this extrasolar system as where we see them in asteroids in the solar system,' added Logan Francis, a co-author from Leiden University. How planets were formed The findings offer compelling evidence that the solid particles forming in the disk around HOPS-315 are the earliest precursors to planetesimals — solid bodies that, through gravitational accumulation, coalesce into planets over time. These components, composed of condensed minerals, represent the foundational seeds from which terrestrial planets like Earth and the cores of gas giants such as Jupiter originate. 'We've always known that the first solid parts of planets, or 'planetesimals,' must form further back in time, at earlier stages,' said McClure. Although previous astronomical research has captured images of infant stars surrounded by protoplanetary disks and has detected giant, Jupiter-sized exoplanets embedded within them, these studies have not been able to observe the initial condensation phase — until now. This new data bridges the observational gap between early disk formation and the eventual emergence of full-sized planets. STORY CONTINUES BELOW THIS AD 'For the first time, we have identified the earliest moment when planet formation is initiated around a star other than our sun,' McClure added. What this means for Earth-like worlds The discovery around HOPS-315 doesn't just illuminate how planets are born — it provides a critical template for understanding the conditions under which systems like ours evolve. With its young sun-like characteristics, similar disk structure, and mineral composition, HOPS-315 may be the most accurate proxy for our early solar system yet discovered. 'This is one of the things we've been waiting for. Astronomers have been thinking about how planetary systems form for a long period of time,' Fred Ciesla of the University of Chicago, who was not involved in the study, told AP. 'There's a rich opportunity here.' 'We're seeing a system that looks like what our solar system looked like when it was just beginning to form,' said Merel van 't Hoff of Purdue University, a co-author of the study. 'This system is one of the best that we know to actually probe some of the processes that happened in our solar system.' Van 't Hoff added that finding more such systems would allow scientists to determine how common Earth-like planets might be across the galaxy. STORY CONTINUES BELOW THIS AD 'Are there Earth-like planets out there or are we like so special that we might not expect it to occur very often?' she asked. What next in HOPS-315? While the exact number and type of planets that might eventually form around HOPS-315 remains unknown, the current structure of its disk suggests it has the potential to produce a full planetary system, possibly similar in scale to our own solar system. With the clear detection of solid mineral formation underway, astronomers now have the first direct evidence of the chemical and physical processes that precede planet formation. This milestone sets the stage for a new phase of research into the origin of planetary systems, particularly the formation of rocky, potentially habitable worlds. 'This study shows that it could be a common process during the earliest stage of planet formation,' McClure avered. Also Watch: With inputs from agencies

A Martian rock and dinosaur skeleton just made auction history — Details inside
At a recent auction in New York, a huge rock from Mars was sold for a record $5.3 million. Weighing over 54 pounds, it's believed to be the biggest piece of Martian rock ever found on Earth– and now, the most expensive meteorite ever sold. But that wasn't the only big moment of the night. A rare dinosaur skeleton was also auctioned and grabbed even more attention, selling for a whopping $30 million. A Martian treasure lands on Earth As per media reports, the meteorite, called NWA 16788, was found in the Sahara Desert in Niger in late 2023 by a meteorite hunter. It is believed that it was thrown off Mars by a huge asteroid hit and travelled more than 140 million miles through space before landing on Earth, as mentioned in an Indian Express report. It was expected to sell for $2 to $4 million, but it went for more. The winning bid was $4.3 million, and after adding auction fees, the final price was $5.3 million. As quoted by the Indian Express, Cassandra Hatton, Vice Chairman for Science and Natural History at Sotheby's, highlighted the rarity of the find, noting, 'This Martian meteorite is the largest piece of Mars we have ever found by a long shot.' She added that it is more than double the size of the previous largest fragment. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like This Could Be the Best Time to Trade Gold in 5 Years IC Markets Learn More Undo The unique composition of the meteorite What makes this Martian rock even more special isn't just how big it is– it makes up nearly 7% of all Mars rocks ever found on Earth. As mentioned in the media report, Sotheby's said it's much bigger than any other known Martian piece and is a type of rock called 'olivine-microgabbroic shergottite,' which means it was formed from lava that cooled down on Mars. Its surface looks smooth and glassy, showing it got extremely hot while entering Earth's atmosphere. Experts confirmed the rock came from Mars by checking its chemical makeup and comparing it with data from NASA's Viking mission, which landed on Mars in 1976. The dinosaur skeleton that sparked a bidding frenzy While the meteorite got a lot of attention, it was a rare Ceratosaurus skeleton that really stood out, selling for an incredible $30.5 million. As mentioned in the Indian Express report is believed that it's the only young Ceratosaurus ever found, and just one of four skeletons of this dinosaur known to exist. It looks a bit like the famous T Rex but is smaller in size. According to the media reports, the bidding began at $6 million– already higher than what was expected– and quickly picked up speed. The price kept rising in jumps of $500,000 and later $1 million until it finally sold for $30.5 million, including auction fees. Sotheby's later confirmed that the buyer, who chose to remain anonymous, plans to loan the skeleton to a public institution. Thumb image: Canva (For representational purposes only)
