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.

UP Cong holds statewide protest seeking probe into FIR against Swami Avimukteshwaranand
Lucknow (PTI): The Uttar Pradesh Congress on Wednesday staged a statewide protest demanding a fair and transparent inquiry into the FIR lodged against Swami Avimukteshwaranand Saraswati and those who filed the complaint against him.
In a statement issued here, the party said memorandums addressed to Prime Minister Narendra Modi were submitted through district magistrates in all districts of the state.
Uttar Pradesh Congress spokesperson Manish Hindvi told PTI that the memorandums were handed over through the district administration in all 75 districts.
In the memorandum, the party alleged that Saraswati and his disciples were "unnecessarily harassed and humiliated" by police on the occasion of Amavasya and were prevented from taking a ritual bath (at the Magh Mela). It further alleged that some disciples were manhandled and taken to a police station.
The memorandum also claimed that an FIR was later registered against Saraswati, his disciple Swami Mukundanand Brahmachari and several unidentified persons in a sexual harassment case. It termed the case a "conspiracy" aimed at tarnishing the seer's reputation.
Citing Articles 25 and 26 of the Constitution, the memorandum stated that these provisions guarantee religious freedom and the right of religious denominations to manage their own affairs.
It described the position of shankaracharya held by Saraswati as "one of the highest spiritual posts in Sanatan tradition" and alleged that the entire episode appeared to have been "orchestrated in a planned manner".
"We request that the background of the persons who got the FIR registered be investigated in a transparent manner by a retired high court judge and strict action be taken against them," the memorandum said.
It also sought a "fair and transparent probe" into the allegations levelled against Saraswati so that the truth could be established.
Earlier, Uttar Pradesh Congress president Ajay Rai had told reporters in Varanasi after meeting Saraswati that the party stood firmly with him.
The Congress said it would continue to press for an impartial inquiry into the entire episode.
On February 21, an FIR was lodged in Prayagraj against Saraswati and his disciple Mukundanand Brahmachari on charges of sexually abusing two persons, including a minor, over the past year at a gurukul and religious congregations, including the recently concluded Magh Mela.
Days after he was booked, Saraswati had said on Monday that he would not oppose his arrest and asserted that the "fabricated story" would be exposed sooner or later.
At a press conference on Wednesday, Saraswati alleged that criminals rule in Uttar Pradesh, level allegations and influence investigations, as he denied having any contact with the two persons for whose alleged sexual abuse he has been booked.
