From boring to bursting: a giant black hole awakens

X-ray data gathered by the Chandra telescope from the center of M31, highlighting the four nuclear sources — S1, SSS, N1, and P2. P2 corresponds to the position of the supermassive black hole at the center of the Andromeda galaxy.

Vision of future solar cell fabrication on the Moon, utilizing raw regolith. Shown are robots that source raw regolith and bring it to a production facility, which fabricates perovskite-based moon solar cells. Later automated rovers or astronauts install the produced solar cells to power future Moon-habitats or even cities.

Components of the Bounce protocol: Each Sending Station may send one or more Merkle Tree roots to the satellite in charge of a slot. The satellite signs a sequence of zero or more roots and sends them to Broadcast Ground Stations which make the roots and the underlying Merkle Tree widespread (i.e., available to the user community).

Three spectra taken by the JWST/NIRSpec superimposed on an image taken by the JWST/NIRCam, two instruments on board the James Webb Space Telescope. The record galaxy is shown in the middle. It appears in red in the image and its spectrum decreases towards the left (short wavelengths). For comparison, the spectra at the top and bottom, in blue and violet, show typical star-forming galaxies at a similar time in cosmic history.

The image columns show the change of Uranus for the four years that STIS observed Uranus across a 20-year period. Over that span of time, the researchers watched the seasons of Uranus as the south polar region darkened going into winter shadow while the north polar region brightened as northern summer approaches.

This JWST image shows the Big Wheel galaxy (in the center) and its cosmic environment. The galaxy is a gigantic rotating disk lying 11.7 billion light-years away. Its spiral disk stretches across 100,000 light-years, making it larger than any other galaxy disk confirmed at this epoch of the universe. The blue blob and some of the other larger objects in the image are galaxies in the nearby universe. The smaller objects tend to be distant galaxies; however, the larger galaxy to the lower left of Big Wheel is part of the same remote galactic structure as Big Wheel. Credit: NASA/ESA

This side-by-side comparison shows a Spitzer Space Telescope Infrared Array Camera image of HH 49/50 (left) versus a Webb image of the same object (right) using the NIRCam (Near-infrared Camera) instrument and MIRI (Mid-infrared Instrument). The Webb image shows intricate details of the heated gas and dust as the protostellar jet slams into the material. Webb also resolves the “fuzzy” object located at the tip of the outflow into a distant spiral galaxy. The Spitzer image shows 3.6-micron light in blue, the 4.5-micron in green, and the 8.0-micron in red (IRAC1, IRAC2, IRAC4). In the Webb image, blue represents light at 2.0-microns (F200W), cyan represents light at 3.3-microns (F335M), green is 4.4-microns (F444W), orange is 4.7-microns (F470N), and red is 7.7-microns (F770W).
