A Delhi boy has discovered a new comet using data from NASA and
European Space Agency's spacecraft-based observatory SOHO that studies
the Sun.
Discovered by Prafull Sharma, a Class XII student of Ahlcon Public
School, the new comet -- SOHO 2333 -- is a fragment believed to have
separated from a relatively larger comet Machholz when it last came
close to the Sun in 2007.
Sharma, who has been associated with
Delhi-based NGO Science Popularisation Association of Communicators and
Educators (SPACE), is part of a world-wide team of comet hunters who
scour through images of the Sun transmitted back to Earth by Solar and
Heliospheric Observatory (SOHO).
The British Astronomical Association also confirmed the find and included it in their list of newly discovered comets.
SOHO
comets are small comets that are usually found in close proximity of
the Sun, Chander Bhushan Devgun, Chairman of SPACE said.
Most of these comets crash into the Sun and are never seen again, he said.
However,
SOHO 2333 appears to he similar to its parent comet Machholz and its
orbit will be determined by the International Astronomical Union.
"Discoveries
like this are really crucial to help us understand the dynamic nature
of comet population, and can help us infer the properties of comets --
the left-over debris from the building of our solar system," Karl
Battams, SOHO Moderator for the Sungrazer programme said.
These comet hunters do not get to name the comets they discover nor do they get monetary rewards.
Around
the same time as Sharma, another comet hunter Liang Liu of China found
one more fragment of comet Machholz which was also designated as a
comet.
Sharma and Liang had joined the Sungrazer project in January this year and this is the first discovery for both of them.
The project allows anyone world-wide to discover comets in images from the ESA/NASA SOHO missions.
