Cosmos television show Archives

With the premiere of the revamped “Cosmos” series, NASA used this opportunity to showcase the imagery and missions that are such a big part of our explorations of the Universe, live-Tweeting during the show:

The Goddard Space Flight Center Flickr page featured a gallery of images from the cosmos, many which are part of the “Cosmos” series. See a sampling of great images below:

This mosaic of M31 merges 330 individual images taken by the Ultraviolet/Optical Telescope aboard NASA's Swift spacecraft. It is the highest-resolution image of the galaxy ever recorded in the ultraviolet. The image shows a region 200,000 light-years wide and 100,000 light-years high (100 arcminutes by 50 arcminutes).

On August 31, 2012 a long filament of solar material that had been hovering in the sun's atmosphere, the corona, erupted out into space at 4:36 p.m. EDT. The coronal mass ejection, or CME, traveled at over 900 miles per second. The CME did not travel directly toward Earth, but did connect with Earth's magnetic environment, or magnetosphere, causing aurora to appear on the night of Monday, September 3. The image above includes an image of Earth to show the size of the CME compared to the size of Earth.

This planetary nebula's simple, graceful appearance is thought to be due to perspective: our view from Earth looking straight into what is actually a barrel-shaped cloud of gas shrugged off by a dying central star. Hot blue gas near the energizing central star gives way to progressively cooler green and yellow gas at greater distances with the coolest red gas along the outer boundary.

Universe Today podcasts with Fraser Cain

The Guide to Space is a series of space and astronomy poddcasts by Fraser Cain, publisher of Universe Today

Near the end of 2019, astronomers watching the red giant Betelgeuse noted how much the star had dimmed, continuing to steadily fade for months.

It’s a variable star, and it’s known to get dimmer and brighter, but the big surprise is that it’s still continuing to dim, recently passing magnitude 1.56 and still getting dimmer. This is unprecedented in the decades that astronomers have been watching the star.

The world’s biggest telescopes are on the case, and the European Southern Observatory released dramatic new images of Betelguese, resolving features on the star’s surface and surrounding area showing how it’s dramatically changed over the course of 2019.
