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.

Badminton coach arrested for raping 16-year-old girl in Bengaluru
Bengaluru, Apr 07 (PTI): A badminton coach was arrested for allegedly raping a 16-year-old girl who was taking training from him, police said on Monday.
The matter came to light after the girl's grandmother found that the minor had sent some of her nude pictures from her (grandmother's) phone to an unknown number and she immediately alerted her parents, they said.
When confronted by her mother, the girl revealed that the coach had sexually abused her on multiple occasions under the guise of giving her additional training sessions and warned her against disclosing about it to anyone, police said.
According to the police, the victim's mother in a complaint stated that their daughter enrolled for badminton coaching at a sports centre here two years ago. The coach allegedly sexually abused and harassed her on multiple occasions. He even took her to his house where he sexually assaulted her.
After her class 10 exam, she went to her grandmother's house and that on March 30 she sent her nude photos from her grandmother's mobile phone to the coach on his insistence, the complainant alleged.
Based on the complaint, a case was registered against the coach, a native of Tamil Nadu, under the Protection of Children from Sexual Offences (POCSO) Act and he was arrested in the case on Thursday, a senior police officer said.
During interrogation, the accused confessed that he had sexually abused the girl on multiple occasions and that he had taken her nude photos which were also found on his phone. Nude photos of other girls were also found on his phone, the officer said.
