NASA's Hubble Telescope Snaps Best Images Yet Of Our First Interstellar Comet




<div _ngcontent-c16 = "" innerhtml = "

Astronomers have used NASA's Hubble Space Telescope to Capture new images of comet 2I / Borisov, the second confirmed interstellar object to be found in our solar system.

Led by David Jewitt of the University of California, Los Angeles, a team has The use of the Hubble image was made in late August 201

7 as it makes our way into the solar system observation.

The image is in a blue sky, it is isolated on a white background expecting this activity to increase, peaking on Dece mber 7 when it makes its closest approach to the Sun at about two times the Earth-Sun distance, or two AU (astronomical units).

 

However, Jewitt and his team wants to use these images to try and work out the size of the nucleus of the comet, which is the hard core around the dust and gas swirls.

Comet 2I / Borisov is known to have originated from another solar system based on its trajectory through our own Solar System that is unbound to our Sun. Kruger-60 about 13 light-years away, the complexities involved in mapping back this trajectory in time could not ever be sure.

But studying the our first interstellar visitor, the asteroid-like 'Oumuamua, was spotted in late 2017 on his way out of the solar system, giving us just weeks to observe it.

Aside from learning its size, shape, and rotation speed, astronomers are also hoping to work out what it is made of – including looking at how much water the comet's ices hold, if much at all. Some rare comets in our solar system are unusually rich in carbon monoxide, for example.

At the moment the comet looks just like any other comet in our own solar system, a fascinating discovery in itself may suggest similar systems. Comets, the icy remnants of a planetary system's formation, have long been thought to be potential carriers of water and even the building blocks of life to protoplanets in a star system.

So comet 2I / Borisov represents a hugely exciting opportunity for astronomers and non-astronomers alike. Earth is rare or common in the universe.

These latest images from Hubble give us a fascinating new insight into this interstellar marvel. With many of the world's most powerful telescopes, so to speak, their eyes in its direction, and its dazzling moment in the Sun's spotlight, its secrets will not remain unknown for much longer.
