Hubble Finds Group of Herbig-Haro Objects within NGC 1333

This image from the NASA/ESA Hubble Space Telescope shows the reflection nebula NGC 1333 and associated Herbig-Haro objects. The picture was snapped by Hubble’s Advanced Camera for Surveys (ACS). The image was made through two filters. The color results from assigning different hues to each monochromatic image associated with an individual filter. Image credit: NASA / ESA / Hubble / K. Stapelfeldt.

The NASA/ESA Hubble Space Telescope has spotted a group of five Herbig-Haro objects — tiny patches of nebulosity associated with newborn stars — within NGC 1333, a reflection nebula located in the constellation of Perseus, about 1,000 light-years away from Earth. This image from the NASA/ESA Hubble Space Telescope shows the reflection nebula NGC 1333 and associated Herbig-Haro objects. The picture was snapped by Hubble’s Advanced Camera...

The galaxy cluster Abell S1063 was observed by the NASA/ESA Hubble Space Telescope as part of the Frontier Fields Program. The huge mass of the cluster -- containing both baryonic matter and dark matter -- acts as cosmic magnification glass and deforms objects behind it. In the past astronomers used this gravitational lensing effect to calculate the distribution of dark matter in galaxy clusters. A more accurate and faster way, however, is to study the intracluster light (visible in blue), which follows the distribution of dark matter. Image credit: NASA / ESA / M. Montes, University of New South Wales.

This 120 second image of comet 46P/Wirtanen was taken December 2, 2018 by an iTelescope 50 mm refractor located at an observatory near Mayhill, New Mexico. The streak below the comet was produced by a rocket body (upper stage) passing through the telescope’s field of view during the exposure. Specifically, the upper stage is the one that placed the Indonesian Garuda 1 communications satellite into geostationary orbit back in February of 2000. At the time of this image, the Garuda 1 upper stage was 15,880 miles (25,556 km) from the observatory; 46P/Wirtanen was 10.3 million miles (16.6 million km) distant. Image credit: NASA.

This artist’s illustration shows a giant cloud of hydrogen streaming off the warm Neptune GJ 3470b. The host star’s intense radiation is heating the hydrogen in the planet’s upper atmosphere to a point where it escapes into space. GJ 3470b is losing hydrogen at a rate 100 times faster than a previously observed warm Neptune whose atmosphere is also evaporating away. Image credit: NASA / ESA / D. Player, STScI.
