Pseudosuchia is a group of archosaurian reptiles, defined as all species more closely related to crocodylians than to birds. Living representatives of Pseudosuchia are all members of Crocodylia, a group of semi-aquatic ambush predators found predominantly in freshwater habitats of the tropics. Whereas crocodylians number fewer than 30 species, more than 700 species of pseudosuchians are known from their 250-million-year fossil record. In new research,...

This Hubble image shows NGC 2210, a globular cluster located 163,000 light-years away in the constellation of Dorado. Also known as ESO 57-71 or LW 423, the cluster was first discovered on January 31, 1835 by the English astronomer John Herschel. The color image is made up of observations from Hubble’s Advanced Camera for Surveys (ACS) and Wide Field Camera 3 (WFC3) and in the ultraviolet, near-infrared, and optical parts of the spectrum. It is based on data obtained through three filters. The color results from assigning different hues to each monochromatic image associated with an individual filter.

The six planets in the HD 110067 system are all smaller than Neptune and revolve around their parent star in a very precise waltz: when the closest planet to the star makes three full revolutions around it, the second one makes exactly two during the same time; this is called a 3:2 resonance; the six planets form a resonant chain in pairs of 3:2, 3:2, 3:2, 4:3, and 4:3, resulting in the closest planet completing six orbits while the outer-most planet does one.

Left: this image from the Multi Unit Spectroscopic Explorer (MUSE) on ESO’s Very Large Telescope shows the parent cloud LHA 120-N 180B in which the HH 1177 system was first observed. Center: this image shows the jets that accompany HH 1177; the top part of the jet is aimed slightly towards us and thus blueshifted; the bottom one is receding from us and thus redshifted. Right: this image from ALMA shows the rotating disk around the star, similarly with sides moving towards and away from us. Image credit: ESO / ALMA / NAOJ / NRAO / McLeod et al.
