Hubble Telescope zooms in on interstellar visitor

NASA's Hubble Space Telescope has given astronomers their best look yet at an interstellar visitor – comet 2I/Borisov – whose speed and trajectory indicate it has come from beyond our solar system. Hubble photographed the comet at a distance of 260 million miles from Earth. This Hubble image, taken on October 12, 2019, is the sharpest view to date of the comet. Hubble reveals a central concentration of dust around the nucleus (which is too small to be seen by Hubble). The comet is falling toward the Sun and will make its closest approach on December 7, 2019, when it will be twice as far from the Sun as Earth. The comet is following a hyperbolic path around the Sun and will exit back into interstellar space. Comet 2I/Borisov is only the second such interstellar object known to have passed through the solar system. In 2017, the first identified interstellar visitor, an object formally named 'Oumuamua, swung within 24 million miles of the Sun before racing out of the solar system.

The Hubble Space Telescope has captured the best pictures yet of our newest interstellar visitor.This comet from outside our solar system is zooming by us at a blistering 110,000 mph (177,000 kph). Hubble caught some glam shots over the weekend from a distance of 260 million miles (420 million kilometers).

In the course of looking for possible signs of Extra-Terrestrial Intelligence (ETI), scientists have had to do some really outside-of-the-box thinking. Since it is a foregone conclusion that many ETIs would be older and more technologically advanced than humanity, those engaged in the Search for Extra-Terrestrial Intelligence (SETI) have to

NASA is about to make an announcement about the Kepler, potentially to say the planet-hunting telescope has finally run out of fuel almost a decade after being launched into space.A tweet from the agency that in the teleconference, it will “provide an update on the status” of the telescope, and

Hubble Takes Spectacular Photo of Vast Galaxy Cluster

The Hubble Space Telescope has captured a spectacular image showing a vast collection of galaxies located around 4 billion light-years from Earth.The cluster, known as Abell 370—located in the constellation Cetus—is the first target of a new Hubble mission known as the BUFFALO survey, which aims to broaden our understanding of
