Clouds Around Galaxy Andromeda
24.10.2022
What are those red clouds surrounding the Andromeda galaxy? This galaxy, M31, is often imaged by planet Earth-based astronomers. As the nearest large spiral galaxy, it is a familiar sight with dark dust lanes, bright yellowish core, and spiral arms traced by clouds of bright blue stars.
Milky Way and Zodiacal Light over Australian Pinnacles
23.10.2022
What strange world is this? Earth. In the foreground of the featured image are the Pinnacles, unusual rock spires in Nambung National Park in Western Australia. Made of ancient sea shells (limestone), how these human-sized picturesque spires formed remains a topic of research. The picturesque panorama was taken in 2017 September.
NGC 1499: The California Nebula
22.10.2022
Drifting through the Orion Arm of the spiral Milky Way Galaxy, this cosmic cloud by chance echoes the outline of California on the west coast of the United States. Our own Sun also lies within the Milky Way's Orion Arm, only about 1,500 light-years from the California Nebula.
Andromeda in Southern Skies
21.10.2022
Looking north from southern New Zealand, the Andromeda Galaxy never gets more than about five degrees above the horizon. As spring comes to the southern hemisphere, in late September Andromeda is highest in the sky around midnight though.
Pillars of Creation
20.10.2022
A now famous picture from the Hubble Space Telescope featured these star forming columns of cold gas and dust light-years long inside M16, the Eagle Nebula, dubbed the Pillars of Creation. This James Webb Space Telescope NIRCam image expands Hubble's exploration of that region in greater detail and depth inside the iconic stellar nursery.
A Galaxy Beyond Stars, Gas, Dust
19.10.2022
Do we dare believe our eyes? When we look at images of space, we often wonder whether they are "real", and just as often the best answer varies. In this case, the scene appears...
Milky Way Auroral Flower
18.10.2022
Could the stem of our Milky Way bloom into an auroral flower? No, not really, even though it may appear that way in todayBs featured all-sky image. On the left, the central plane of our home galaxy extends from the horizon past the middle of the sky.
X Ray Rings Around a Gamma Ray Burst
17.10.2022
Why would x-ray rings appear around a gamma-ray burst? The surprising answer has little to do with the explosion itself but rather with light reflected off areas of dust-laden gas in our own Milky Way Galaxy.
Barred Spiral Galaxy NGC 1300
16.10.2022
Across the center of this spiral galaxy is a bar. And at the center of this bar is smaller spiral. And at the center of that spiralbis a supermassivebblack hole.b This all happens...
GRB 221009A
15.10.2022
Gamma-ray burst GRB 221009A likely signals the birth of a new black hole, formed at the core of a collapsing star long ago in the distant universe. The extremely powerful blast is depicted in this animated gif constructed using data from the Fermi Gamma Ray Space Telescope.
