NASA Astronomy Picture of the Day:

Point your telescope toward the high flying constellation Pegasus and you can find this cosmic expanse of Milky Way stars and distant galaxies. NGC 7814 is centered in the sharp field of view that would almost be covered by a full moon. NGC 7814 is sometimes called the Little Sombrero for its resemblance to the brighter more famous M104, the Sombrero Galaxy. Both Sombrero and Little Sombrero are spiral galaxies seen edge-on, and both have extensive halos and central bulges cut by a thin disk with thinner dust lanes in silhouette. In fact, NGC 7814 is some 40 million light-years away and an estimated 60,000 light-years across. That actually makes the Little Sombrero about the same physical size as its better known namesake, appearing smaller and fainter only because it is farther away.

NASA Astronomy Picture of the Day:

The North America nebula on the sky can do what the North America continent on Earth cannot -- form stars. Specifically, in analogy to the Earth-confined continent, the bright part that appears as the east coast is actually a hot bed of gas, dust, and newly formed stars known as the Cygnus Wall. The featured image shows the star forming wall lit and eroded by bright young stars and partly hidden by the dark dust they have created. The part of the North America nebula (NGC 7000) shown spans about 50 light years and lies about 1,500 light years away toward the constellation of the Swan (Cygnus).

Tompot blenny (Parablennius gattorugine), Arrábida National Park, Portugal. Note: no FP of this species. It can be found in shallow, coastal waters off western Europe and northern Africa and in the Mediterranean. The tompot blenny is a relatively large blenny that can grow up to 30 centimetres (12 in) in length. There is a single branched tentacle over each of its eyes. It's very territorial and its territory is centred around a crevice in the rocky reef which the fish uses for shelter. It occurs in shallow seas at depths of 3–32 metres (9.8–105.0 ft) and is crepuscular, being active mainly at dawn and at dusk. It has sharp, comb-like teeth which it uses to scrape food from the substrate. It feeds on sea anemones and other invertebrates such as prawns and other crustaceans.

What's that in the sky? Above the city, above most clouds, far in the distance: it's a comet. Pictured, the impressive tail of Comet C/2024 G3 (ATLAS) was imaged from Brasília, Brazil four days ago. Last week the evolving comet rounded the Sun well inside the orbit of planet Mercury, going so close there was early concern that it might break up -- and recent evidence that it really did. At one point near perihelion, Comet ATLAS was so bright that sightings were even reported during the day -- over the bright sky near the Sun -- by careful observers. Over the past few days, Comet ATLAS has developed a long tail that has been partly visible with unaided eyes after sunset, most notably in Earth's southern hemisphere.
