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).

Hubble Spots “Impossible” Debris Disk Around a Black Hole

Hubble Spots

The Hubble Space Telescope is like an old dog that is constantly teaching the astronomical community new tricks. In the course of its almost thirty years in operation, it has revealed vital data about the expansion of the Universe, its age, the Milky Way, supermassive black holes (SMBHs), other star

Hubble peers at cosmic blue bauble

Messier 3: Containing an incredible half-million stars, this 8-billion-year-old cosmic bauble is one of the largest and brightest globular clusters ever discovered.

Globular clusters are inherently beautiful objects, but the subject of this NASA/ESA Hubble Space Telescope image, Messier 3, is commonly acknowledged to be one of the most beautiful of them all.Containing an incredible half-million stars, this 8-billion-year-old cosmic bauble is one of the largest and brightest globular clusters ever discovered.

In Search of Missing Worlds, Hubble Finds a Fast Evaporating Exoplanet

This artist’s illustration shows a giant cloud of hydrogen streaming off a warm, Neptune-sized planet just 97 light-years from Earth.

Fishermen would be puzzled if they netted only big and little fish, but few medium-sized fish. Astronomers likewise have been perplexed in conducting a census of star-hugging extrasolar planets. They have found hot Jupiter-sized planets and hot super-Earths (planets no more than 1.5 times Earth’s diameter). These planets are scorching

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
