Astronomers find first carbon-rich asteroid in Kuiper Belt
Washington, May 10: Astronomers have discovered an unusual carbon-rich asteroid in the Kuiper Belt -- the first of its kind to be confirmed in the cold outer reaches of the solar system.
This object, designated 2004 EW95, likely formed in the asteroid belt between Mars and Jupiter and has been flung billions of kilometres from its origin to its current home in the Kuiper Belt, the study said.
The researchers found that the asteroid's reflectance spectrum -- the specific pattern of wavelengths of light reflected from an object -- was different to that of similar small Kuiper Belt Objects (KBOs), which typically have uninteresting, featureless spectra that reveal little information about their composition.
"The reflectance spectrum of 2004 EW95 was clearly distinct from the other observed outer Solar System objects," explained lead author Tom Seccull of Queen's University Belfast in Britain
"It looked enough of a weirdo for us to take a closer look," Seccull added.
Theoretical models of the early days of our solar system predict that after the gas giants formed they rampaged through the solar system, ejecting small rocky bodies from the inner solar system to far-flung orbits at great distances from the Sun.
In particular, these models suggest that the Kuiper Belt -- a cold region beyond the orbit of Neptune -- should contain a small fraction of rocky bodies from the inner solar system, such as carbon-rich asteroids, referred to as carbonaceous asteroids.
The new study, published in The Astrophysical Journal, presented evidence for the first reliably-observed carbonaceous asteroid in the Kuiper Belt, providing strong support for these theoretical models of our solar system's troubled youth.
After measurements from multiple instruments at European Southern Observatory's Very Large Telescope (VLT), the team of astronomers was able to measure the composition of the object.
The results suggest that it originally formed in the inner solar system and must have since migrated outwards.

Allu Arjun didn't leave theatre despite being told about woman's death: Hyderabad police
Hyderabad, Dec 22: Top Telugu actor Allu Arjun did not leave the theatre during the screening of 'Pushpa-2' on December 4 despite being told to do so in view of a stampede in which a woman died, police officials claimed on on Sunday.
Speaking at a press conference on the annual round-up of 2024, city police commissioner C V Anand showed a video, made by police, on the situation that prevailed when the stampede occurred.
The video was made by collating footage, including from news channels and cell phone clips. It suggests the actor remained in the theatre till the midnight.
Anand did not make any comment on the video, but said the media can draw its own conclusions.
A police official talked about the sequence of events on the fateful night of December 4.
He said that he and other police officials informed a manager of Allu Arjun about the death of the woman and told him that the situation was out of control. He indicated that they were not allowed to meet the actor.
Allu Arjun's staff members told them that they would convey the matter to the actor but did not do so, he said.
The official said he later managed to reach the actor, told him about the woman's death and asked him to leave the theatre so that the fans don't harm each other while trying to catch a glimpse of him.
The official also told the actor that security arrangements would be made for his exit.
However, the actor said he would go only after watching the film, the police official said.
Later, accompanied by a senior officer, the official went inside and brought the actor out, he said.
Amid allegations that bouncers hired by Allu Arjun pushed crowds as well as policemen when the stampede occurred at the cinema hall, the police commissioner warned that stringent action as per law would be taken if THE bouncers indeed misbehaved with the police on duty.
The VIPs would be made responsible for the behaviour of the bouncers hired by them, he said.
Asked if the police would appeal against the interim bail granted to Allu Arjun, the commissioner refused to give a direct response, just saying it is part of the investigation.
What course of action is taken would be known in the days to come, he said.
He also declined to comment when asked if the family of the deceased told him about Allu Arjun's team or film production team allegedly threatening them not to speak on the issue.
Meanwhile, state Cinematography Minister Komatireddy Venkat Reddy found fault with Allu Arjun responding on Saturday to the debate in the Legislative Assembly.
The minister, who observed that the actor should have respect for the government and the chief minister, demanded an apology from Allu Arjun to the government and the CM.
"This government is never vindictive. As Cinematography Minister, we allowed benefit shows and hiking ticket prices to promote the film industry," he said.
However, Union Minister of State for Home Bandi Sanjay Kumar found fault with CM Revanth Reddy for his comments on Allu Arjun in the Assembly on Saturday.
The comments of the CM sounded like character assassination of Allu Arjun and hurting the Telugu film industry, he alleged in a statement.
Later in the day, Sanjay Kumar visited a boy who is undergoing treatment in a hospital after being injured in the stampede.
"Consoled his father over the heartbreaking loss of his wife, Revathi. I pray to god that Sritej recovers at the earliest. Assured support to the family in this difficult time," Kumar said on X.
Earlier in the day, state DGP Jitender told reporters in Karimnagar district that film personalities and all others should understand that safety and security of citizens is utmost important, and also conduct themselves accordingly.
