APOD: 2022-11-14 - NGC 7380: The Wizard Nebula (Narrated by Emma)
Astronomy Picture of the Day - November 14th, 2022 - NGC 7380: The Wizard Nebula (Narrated by Emma)
What powers are being wielded in the Wizard Nebula? Gravitation strong enough to form stars, and stellar winds and radiations powerful enough to create and dissolve towers of gas. Located only 8,000 light years away, the Wizard nebula, featured here, surrounds developing open star cluster NGC 7380. Visually, the interplay of stars, gas, and dust has created a shape that appears to some like a fictional medieval sorcerer. The active star forming region spans 100 about light years, making it appear larger than the angular extent of the Moon. The Wizard Nebula can be located with a small telescope toward the constellation of the King of Aethiopia (Cepheus). Although the nebula may last only a few million years, some of the stars being formed may outlive our Sun.

apod-2022-08-17-stargate-milky-way
Astronomy Picture of the Day - August 17th, 2022 - Stargate Milky Way (Narrated by Salli)
There is a huge gate of stars in the sky, and you pass through it twice a day. The stargate is actually our Milky Way Galaxy, and it is the spin of the Earth that appears to propel you through it. More typically, the central band of our Milky Way appears as a faint band stretching across the sky, only visible in away from bright city lights. In a long-exposure wide-angle image from a dark location like this, though, the Milky Way's central plane is easily visible. The featured picture is a digital composite involving multiple exposures taken on the same night and with the same camera, but employing a stereographic projection that causes the Milky Way to appear as a giant circular portal. Inside the stargate-like arc of our Galaxy is a faint stripe called zodiacal light -- sunlight reflected by dust in our Solar System. In the foreground are cacti and dry rocks found in the rough terrain of the high desert of Chile, not far from the El Sauce Observatory and the developing Vera Rubin Observatory, the latter expected to begin routine operations in 2024.

apod-2022-08-21-the-spinning-pulsar-of
Astronomy Picture of the Day - August 21st, 2022 - The Spinning Pulsar of the Crab Nebula (Narrated by Brian)
At the core of the Crab Nebula lies a city-sized, magnetized neutron star spinning 30 times a second. Known as the Crab Pulsar, it is the bright spot in the center of the gaseous swirl at the nebula's core. About twelve light-years across, the spectacular picture frames the glowing gas, cavities and swirling filaments near the Crab Nebula's center. The featured picture combines visible light from the Hubble Space Telescope in purple, X-ray light from the Chandra X-ray Observatory in blue, and infrared light from the Spitzer Space Telescope in red. Like a cosmic dynamo the Crab pulsar powers the emission from the nebula, driving a shock wave through surrounding material and accelerating the spiraling electrons. With more mass than the Sun and the density of an atomic nucleus,the spinning pulsar is the collapsed core of a massive star that exploded. The outer parts of the Crab Nebula are the expanding remnants of the star's component gasses. The supernova explosion was witnessed on planet Earth in the year 1054.

apod-2022-06-11-the-road-and-the-milky
Astronomy Picture of the Day - June 11th, 2022 - The Road and the Milky Way (Narrated by Emma)
At night you can follow this road as it passes through the Dark Sky Alqueva reserve not too far from Alentejo, Portugal. Or you could stop, look up, and follow the Milky Way through the sky. Both stretch from horizon to horizon in this 180 degree panorama recorded on June 3. Our galaxy's name, the Milky Way, does refer to its appearance as a milky path in the sky. The word galaxy itself derives from the Greek for milk. From our fair planet the arc of the Milky Way is most easily visible on moonless nights from dark sky areas, though not quite so bright or colorful as in this image. The glowing celestial band is due to the collective light of myriad stars along the galactic plane too faint to be distinguished individually. The diffuse starlight is cut by dark swaths of the galaxy's obscuring interstellar dust clouds. Standing above the Milky Way arc near the top of this panoramic nightscape is bright star Vega, with the galaxy's central bulge near the horizon at the right.

apod-2020-09-08-gw190521-unexpected
Astronomy Picture of the Day - September 8th, 2020 - GW190521: Unexpected Black Holes Collide (Narrated by Amy)
How do black holes like this form? The two black holes that spiraled together to produce the gravitational wave event GW190521 were not only the most massive black holes ever seen by LIGO and VIRGO so far, their masses -- 66 and 85 solar masses -- were unprecedented and unexpected. Lower mass black holes, below about 65 solar masses are known to form in supernova explosions. Conversely, higher mass black holes, above about 135 solar masses, are thought to be created by very massive stars imploding after they use up their weight-bearing nuclear-fusion-producing elements. How such intermediate mass black holes came to exist is yet unknown, although one hypothesis holds that they result from consecutive collisions of stars and black holes in dense star clusters. Featured is an illustration of the black holes just before collision, annotated with arrows indicating their spin axes. In the illustration, the spiral waves indicate the production of gravitational radiation, while the surrounding stars highlight the possibility that the merger occurred in a star cluster. Seen last year but emanating from an epoch when the universe was only about half its present age (z ~ 0.8), black hole merger GW190521 is the farthest yet detected, to within measurement errors.

Astronomy Picture of the Day - September 14th, 2021 - Mars Panorama 360 from Curiosity (Narrated by Amy)
Which way up Mount Sharp? In early September, the robotic rover Curiosity continued its ascent up the central peak of Gale Crater, searching for more clues about ancient water and further evidence that Mars could once have been capable of supporting life. On this recent Martian morning, before exploratory drilling, the rolling rover took this 360-degree panorama, in part to help Curiosity's human team back on Earth access the landscape and chart possible future routes. In the horizontally-compressed featured image, an amazing vista across Mars was captured, complete with layered hills, red rocky ground, gray drifting sand, and a dusty atmosphere. The hill just left of center has been dubbed Maria Gordon Notch in honor of a famous Scottish geologist. The current plan is to direct Curiosity to approach, study, and pass just to the right of Gordon Notch on its exploratory trek.

apod-2023-08-18-northern-pluto-(narrated
Astronomy Picture of the Day - August 18th, 2023 - Northern Pluto (Narrated by Brian)
Gaze across the frozen canyons of northern Pluto in this contrast enhanced color scene. The image data used to construct it was acquired in July 2015 by the New Horizons spacecraft as it made the first reconnaissance flight through the remote Pluto system six billion kilometers from the Sun. Now known as Lowell Regio, the region was named for Percival Lowell, founder of the Lowell Observatory. Also famous for his speculation that there were canals on Mars, Lowell started the search that ultimately led to Pluto's discovery in 1930 by Clyde Tombaugh. In this frame Pluto's North Pole is above and left of center. The pale bluish floor of the broad canyon on the left is about 70 kilometers (45 miles) wide, running vertically toward the south. Higher elevations take on a yellowish hue. New Horizon's measurements were used to determine that in addition to nitrogen ice, methane ice is abundant across Lowell Regio. So far, Pluto is the only Solar System world named by an 11-year-old girl.

Astronomy Picture of the Day - April 19th, 2022 - Stars and Globules in the Running Chicken Nebula (Narrated by Amy)
The eggs from this gigantic chicken may form into stars. The featured emission nebula, shown in scientifically assigned colors, is cataloged as IC 2944 but known as the Running Chicken Nebula for the shape of its greater appearance. Seen toward the bottom of the image are small, dark molecular clouds rich in obscuring cosmic dust. Called Thackeray's Globules for their discoverer, these "eggs" are potential sites for the gravitational condensation of new stars, although their fates are uncertain as they are also being rapidly eroded away by the intense radiation from nearby young stars. Together with patchy glowing gas and complex regions of reflecting dust, these massive and energetic stars form the open cluster Collinder 249. This gorgeous skyscape spans about 60 light-years at the nebula's estimated 6,500 light-year distance.
