This map shows the CMB’s polarization signal, as measured by the Planck satellite in 2015. The top and bottom insets show the difference between filtering the data on particular angular scales of 5 degrees and 1/3 of a degree, respectively....
The nearby dwarf galaxy Leo P, whose individual blue stars are clearly visible, was imaged by JWST in order to resolve the various old and young populations inside of it. The cosmic lessons it taught us about how star-formation proceeded...
The Atacama Large Millimetre/submillimetre Array, or ALMA, is the most powerful, highest-resolution array of radio telescopes in the world. Although it only has the light-gathering power of all its dishes, combined, it has the resolution of the space between the...
This three panel view shows Hubble’s optical views of the Ring Nebula (L), SMA’s view of the carbon monoxide in the Ring Nebula (mid), and the location of the neutral CO, in contours, versus JWST observations of various other features,...
This side-by-side view of galaxy cluster SMACS 0723 shows the MIRI (left) and NIRCam (right) views of this region from JWST. Note that although there’s a bright galaxy cluster at the center of the image, the most interesting objects are...
The proton isn’t just made of three valence quarks, but rather contains a substructure that is an intricate and dynamic system of quarks (and antiquarks) and gluons inside. The nuclear force acts like a spring, with negligible force when unstretched...
These six “little red dot” galaxies are examples of objects that, if their brightness was caused by the stars within them alone, could not have grown to such high masses in such short amounts of cosmic time under our currently...
This artist’s depiction shows a tidal disruption event around an active black hole. Whereas most active black holes that have jets are seen to possess those jets constantly, the first example of a jetless active black hole having a radio...
The galaxy Centaurus A is the closest example of an active galaxy to Earth, with its high-energy jets caused by electromagnetic acceleration around the central black hole. The extent of its jets are far smaller than the jets that Chandra...
The featured image shows the star RR Lyrae, as imaged by the digitized sky survey back at the turn of the century, using data from the Palomar and UK Schmidt telescopes. (Credit: Digitized Sky Survey — STScI/NASA)Most stars shine with...
