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.

BCB official calling Tamim 'an Indian agent' invites wrath of Bangladesh players
Dhaka (PTI): A senior Bangladesh Cricket Board (BCB) official calling former captain Tamim Iqbal "an Indian agent" has not gone down well with the players in the country.
Tamim, one of the finest openers to have come out of Bangladesh, had advised the BCB to not be driven by emotion while deciding the way forward on the national team's participation in the T20 World Cup in India.
Nazmul, chairman of BCB finance committee, called the left-hander opener "an Indian agent" in a Facebook post.
"This time, the people of Bangladesh witnessed, with their own eyes, the emergence of yet another proven Indian agent," he wrote.
The post received immediate backlash from former and current cricketers, including Taskin Ahmed, Momimul Haque and Taijul Islam.
Even the Cricketers' Welfare Association of Bangladesh (CWAB) expressed shock at Nazmul's comments.
"A comment made by BCB director M Nazmul Islam regarding former national captain Tamim Iqbal has come to the attention of the Cricketers' Welfare Association of Bangladesh. We are stunned, shocked, and outraged by it.
"Such a remark by a board official about the most successful opener in Bangladesh's history, who represented the country for 16 years, is utterly condemnable.
"Not only because it concerns a player like Tamim, but such comments about any cricketer of the country are unacceptable and insulting to the entire cricketing community," the players' body said in a statement.
The 36-year-old Tamim played 70 Tests, 243 ODIs and 78 T20 Internationals for his country in a fairly accomplished career.
"We strongly protest against this comment. When a responsible board director makes such remarks on a public platform, it also raises serious questions about the code of conduct of board officials," it said.
"We have already submitted a protest letter to the BCB president, demanding a public apology from the concerned board director and that he be brought under accountability. We hope the BCB president will take appropriate action as soon as possible," CWAB added.
Bangladesh wrote to the International Cricket Council to move their T20 World Cup games out of India after the BCCI instructed IPL franchise KKR to release Mustafizur Rahman ahead of the 2026 edition without giving a specific reason.
"Cricket is the life of Bangladesh. A recent comment surrounding a former national captain who has made a major contribution to the game has caused many to reflect," said pacer Taskin.
"I believe that such remarks directed at a former cricketer of the country are not helpful in the interest of Bangladesh cricket. I hope the concerned authorities will consider the matter seriously and adopt a more responsible stance in the future," he said.
Mominul added: "The comment made by BCB director M Nazmul Islam regarding former national captain Tamim Iqbal is completely unacceptable and insulting to the country's cricketing community. Such behaviour towards a cricketer is in direct conflict with the board's responsibility and ethics," said Mominul.
"A senior cricketer was not given even the minimum respect; instead, he was deliberately humiliated in public. Such remarks show a lack of even basic decorum regarding where and how to speak while holding such a high responsibility.
"I strongly condemn this comment and firmly demand a public apology from the concerned director and that he be brought under accountability. I call upon the BCB to take swift and strict action," said Mominul.
