Massive stars in our Milky Way Galaxy live spectacular lives. Collapsing from vast cosmic clouds, their nuclear furnaces ignite and create heavy elements in their cores. After a few million years, the enriched material is blasted back into interstellar space where star... Continue Reading →
Hubble Space Telescope’s iconic images and scientific breakthroughs have redefined our view of the Universe. To commemorate three decades of scientific discoveries, this image is one of the most photogenic examples of the many turbulent stellar nurseries the telescope has... Continue Reading →
This animation shows a series of views of the Sun captured with the Extreme Ultraviolet Imager (EUI) on ESA’s Solar Orbiter on 30 May 2020. They show the Sun’s appearance at a wavelength of 17 nanometers, which is in the... Continue Reading →
https://www.youtube.com/watch?v=aokGqxVdpz0&feature=emb_logo Yes, but have you seen a movie of Jupiter and Saturn's Great Conjunction? The featured time-lapse video was composed from a series of images taken from Thailand and shows the two giant planets as they angularly passed about a tenth of a degree... Continue Reading →
The prominences of the Sun are solar filaments of matter projected above its surface and characterizing the activity of the Sun. This activity seems to vary by up to another within a cycle.In absolute terms, solar activity is regulated by a cycle... Continue Reading →
Clouds of glowing hydrogen gas fill this colorful skyscape in the faint but fanciful constellation Monoceros, the Unicorn. A star forming region cataloged as NGC 2264, the complex jumble of cosmic gas and dust is about 2,700 light-years distant and mixes reddish emission... Continue Reading →
Jupiter and Saturn have gradually moved closer to each other over for months, and on December 21, the two worlds will be at their closest, around 1/5 of a full Moon apart. This is close enough that many telescopes may... Continue Reading →
Are stars still forming in the Milky Way's satellite galaxies? Found among the Small Magellanic Cloud's (SMC's) clusters and nebulas, NGC 346 is a star forming region about 200 light-years across, pictured here in the center of a Hubble Space Telescope image. A satellite galaxy of the Milky... Continue Reading →
Surprisingly reminiscent of The Great Nebula in Orion, The Great Turkey Nebula spans this creative field of view. Of course if it were the Orion Nebula it would be our closest large stellar nursery, found at the edge of a large molecular... Continue Reading →
