Astronomers spot 'interstellar object' speeding through solar system
An "interstellar object" is speeding toward the inner solar system, where Earth is located, astronomers have confirmed. The object -- likely a comet -- was first detected in data collected between by the Asteroid Terrestrial-impact Last Alert System, or ATLAS -- an asteroid impact early warning system in Rio Hurtado, Chile, funded by NASA, the space agency announced on Tuesday. MORE: NASA detects new planet with temperatures that suggest habitable conditions Properties such as a marginal coma and short tail indicate signs of cometary activity, according to the Minor Planet Center. Numerous telescopes have reported additional observations since the object was first reported, NASA said. Observations from three different ATLAS telescopes around the world -- as well as the Zwicky Transient Facility at the Palomar Observatory in San Diego County, California -- dating back to June 14 were gathered and provided data that supports the existence of the comet, according to a NASA update released Wednesday. It appears to be originating from interstellar space, arriving from the direction of the constellation Sagittarius, and is currently about 420 million miles from Earth, according to NASA. The comet poses no threat to Earth and will remain at a distance of at least 150 million miles, astronomers said. It is estimated to reach its closest approach to the sun around Oct. 30, where it will cross at about 130 million miles away, just inside the orbit of Mars, according to NASA.

It's traveling at a speed of about 152,000 mph and approaching the inner solar system from the bar of the Milky Way, Live Science reported. Its trajectory suggests it did not originate in this solar system, according to This is only the third time in history that an interstellar object entering the inner solar system has been recorded. A cigar-shaped interstellar object called "Oumuamua," the Hawaiian word for "scout," was detected in 2017. And in 2019, an object named "21/Borisov" -- a comet that likely strayed from another star system -- was located. MORE: Asteroid nearly hits Earth in Siberia, with a 2nd massive asteroid passing this week Astronomers will continue to investigate the size and physical properties of the comet through September, after which it will pass too close to the sun to remain visible, NASA said. The comet is expected to reappear on the other side of the sun in early December, NASA said.

Astronomers track object from outside the solar system
Scientists have discovered what might be only the third known interstellar object to pass through our solar system, the European Space Agency says. The harmless object is currently near Jupiter hundreds of millions of kilometres away and moving toward Mars but it should get no closer to the sun than that, according to scientists. It is too soon to know whether the object, designated for now as A11pl3Z, is a rocky asteroid or a icy comet or how big and what shape it is. More observations are needed to confirm its origins. NASA said it is monitoring the situation. Astrophysicist Josep Trigo-Rodriguez of the Institute of Space Sciences near Barcelona, Spain, believes it is an interstellar object based on its odd path and extreme speed cutting through the solar system. He estimates its size at about 40km across. The first confirmed interstellar visitor was in 2017. It was dubbed Oumuamua, Hawaiian for scout, in honour of the observatory in Hawaii that discovered it. Classified at first as an asteroid, the elongated Oumuamua has since showed signs of being a comet. The second object confirmed to have strayed from another star system into our own is 21/Borisov, discovered in 2019 and believed to be a comet.

Astronomers track object that may have originated outside the solar system
CAPE CANAVERAL, Fla. -- Astronomers are monitoring an object headed our way that may have wandered over from another star system. Scientists have discovered what might be only the third known interstellar object to pass through our solar system, the European Space Agency said Wednesday. The harmless object is currently near Jupiter hundreds of millions of miles (kilometers) away and moving toward Mars, but it should get no closer to the sun than that, according to scientists. It's too soon to know whether the object, designated for now as A11pl3Z, is a rocky asteroid or a icy comet, or how big and what shape it is. More observations are needed to confirm its origins. NASA said it is monitoring the situation. Astrophysicist Josep Trigo-Rodriguez of the Institute of Space Sciences near Barcelona, Spain, believes it is an interstellar object based on its odd path and extreme speed cutting through the solar system. He estimates its size at roughly 25 miles (40 kilometers) across. The first confirmed interstellar visitor was in 2017. It was dubbed Oumuamua, Hawaiian for scout, in honor of the observatory in Hawaii that discovered it.

A Strange Signal Is Coming From Space Every 44 Minutes, Scientists Are Baffled
Last Updated: According to Professor Nanda Rea of Spain's Institute of Space Sciences, the discovery hints at the presence of many more such unknown objects hiding across the cosmos A strange celestial object, unlike anything ever observed before, has been discovered by astronomers in Australia. The detection of ASKAP J1832-0911, an object that emits radio and X-ray signals every 44 minutes, is being hailed as a breakthrough that could reshape how scientists understand the universe. The object sends out powerful pulses that last for about two minutes each. These signals were picked up simultaneously by two major observatories: Australia's ASKAP (Australian Square Kilometre Array Pathfinder) radio telescope and NASA's Chandra X-ray Observatory. The rare synchronicity of this observation has made the discovery all the more remarkable. Dr Andy Wang from Curtin University, who was part of the research team, described the find as 'like discovering a needle in a haystack". This object doesn't behave like anything we've ever seen before, he added. ASKAP J1832-0911 appears to belong to a relatively new class of celestial phenomena known as Long-Period Transients, or LPTs. These objects were first identified in 2022 and are known for emitting signals over unusually long intervals. However, this is the first time that any LPT has been observed sending out X-rays along with radio waves. What could it be? Scientists are still unsure. One theory suggests that the object could be a magnetar, a remnant core of a collapsed star with an extremely strong magnetic field. Another hypothesis proposes it may be part of a binary star system involving a highly magnetic white dwarf. But even these explanations do not fully account for its unusual behaviour. According to Professor Nanda Rea of Spain's Institute of Space Sciences, the discovery hints at the presence of many more such unknown objects hiding across the cosmos. 'This is just the beginning," she said, adding that the fact that they caught the signal in both radio and X-ray frequencies at the same time shows that they were on the verge of something bigger. The dual-frequency nature of the signals could help astronomers develop new tools and methods for identifying similar phenomena, potentially uncovering more hidden secrets of the universe. For now, ASKAP J1832-0911 remains an enigma, but one that may open new windows into the unknown chapters of space. First Published: June 09, 2025, 17:06 IST
