Get into a little “Hubble trouble” with this music video by NPR’s Adam Cole, aka Skunk Bear. Produced in honor of the 25th anniversary of the space telescope’s launch aboard Discovery STS-31 on April 24, 1990, the video is a parody of Iggy Azalea’s “Trouble” and, in my opinion, surpasses it astronomically.
(See what I did there?)
The 72-mile (116-km) -wide crater Adedin is seen at an oblique angle in this mosaic made from images acquired by NASA’s MESSENGER spacecraft. The angle highlights the crater’s central peak complex which surrounds a shallow depression that could have a volcanic origin, as well as fine cracks in the floor of its basin and a slumped and terraced section of its far wall. The crater was named after the Bangladeshi painter Zainul Abedin (1914-1976).
And I suggest you enjoy it – it will be one of the last images we see from MESSENGER!
After a brief period of silence (due to its position on the dwarf planet’s night side) NASA’s Dawn spacecraft is now sending back images from orbit around Ceres, revealing amazing details of its surface and giving another look at those mystery “bright spots” that have intrigued scientists since their discovery in 2003.
The animation above shows Ceres’ northern hemisphere as it rotated into the sunlight on April 14. The brightest bright spot can be seen in the crater at right – as Dawn was on approach earlier this year it resolved that spot into two distinct regions.
Scientists still aren’t sure exactly what those are, but soon Dawn will be getting an even better look.
Our Sun may be made up of 98% hydrogen and helium but the remaining two percent comprises many other elements, detectable by their unique absorption lines within the gamut of white light we receive on Earth. One of those elements is calcium, which exists in ionized form in relatively tiny amounts in the Sun’s chromosphere – but still enough to allow images to be made using special filters aligned to the wavelength of its absorption line. And this is precisely what photographer Alan Friedman did on April 12, 2015 when he captured the image above!
On Tuesday, April 14, SpaceX launched its Dragon cargo vehicle aboard a Falcon 9 rocket from Cape Canaveral, sending over two tons of supplies up to the crew of the ISS. While the launch was a success and everything went smoothly for Dragon’s CRS-6 mission (despite a single day’s launch delay due to weather) the experimental landing of the Falcon 9’s first stage onto SpaceX’s autonomous drone ship named “Just Read the Instructions” didn’t work out so well… as you will see in the video above.
UPDATE 4/16: Here’s video footage of the landing attempt from the deck of the ship. So close!
After the landing attempt SpaceX CEO Elon Musk tweeted “Rocket landed on droneship, but too hard for survival.” Yeah, now I see what he meant. It’s actually quite surreal to watch – definitely not something you see every day!
Still, it really wasn’t that far off (it did make it onto the ship!) and with a bit more tweaking this concept of a reusable first stage should soon become a reality for the company. It was only the second live attempt, after all, and SpaceX has six more launches to go in its CRS contract with NASA. CRS-7 is slated to launch on June 19…perhaps third time’s the charm?
Watch the launch of the CRS-6 mission below.

We’re all used to seeing fantastic images of Saturn and its family of moons from NASA’s Cassini spacecraft, which has spent the last decade in orbit around the ringed world. But every now and then Cassini aims its cameras outwards, capturing images of the sky beyond Saturn – just like we might look up at the stars from here on Earth. And while it’s not designed to be a deep-space observatory like Hubble or Subaru (or even like a modest backyard telescope, really) Cassini can still resolve many of the same stars we can easily see in the night sky… and, on April 12, 2015, it spotted something much farther away: the Sombrero Galaxy (M104), 29 million light-years distant!
Coincidentally Cassini grabbed its image of M104 exactly five years after it was imaged with Japan’s Subaru Telescope, located atop Mauna Kea.
