Hubble Space Telescope | Hubble Timelapse of Interstellar Comet 2I/Borisov @hubblespacetelescope | Uploaded October 2019 | Updated October 2024, 9 hours ago.
This is a time-lapse sequence compressing Hubble Space Telescope observations of Comet 2I/Borisov, spanning a seven-hour period. As the second known interstellar object to enter our solar system, the comet is moving along at a breakneck speed of 110,000 miles per hour. To photograph the comet Hubble has to track it, like a photographer tracking a racetrack horse. Therefore, background stars are streaked in the exposure frames. An artificial satellite also crosses the field of view. Hubble reveals a central concentration of dust around an unseen solid icy nucleus. 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 dubbed ‘Oumuamua, swung within 24 million miles of the Sun before racing out of the solar system.

Herbig Haro 666 is a young star that is shooting out narrow collimated jets in opposite directions. The jets are a byproduct of material falling onto to the star. The material is heated and then escapes along the star’s spin axis. Blazing across space at 200,000 miles per hour, the jets provide a way for the star to slow its spin by carrying off angular momentum. The star is hidden deep within the obscuring cloud of gas and dust shown in the Hubble visible-light image. In Hubble’s infrared view, the cloud mostly disappears, revealing the stars within. The jets will extend out to a light-year before dissipating. Jets are a dramatic example of the interaction between stars and the gas and dust that surrounds them.
