Cute Science Video Alert: The Story of Stars

Like people, stars are found in all colors and sizes. They can range from small, sassy red dwarfs to giant blue beasts. In fact there are seven main types of stars, grouped by their apparent colors (and thus temperatures) and classified as O, B, A, F, G, K, or M in order of hottest to coolest. (Learn more about…

These Photos Taken from the Moon Show Lots and Lots of Stars

One of the favorite allegations by those who continue to be skeptical of the Apollo moon landings is that there are no stars visible in the photographs taken by the astronauts while they were “supposedly” on the Moon. Now while there’s a rather short but succinct list of why that’s the case (and feel free to review those…

This Nebula Really Stinks!

This image from the Hubble Space Telescope shows the Calabash Nebula, the cosmic death throes of a low-mass star like our Sun. Caught during the astronomically brief phase between a red giant and a planetary nebula, the star is ejecting much of its mass out into space at velocities of over 620,000 mph. So why does it “stink?” The bright…

Cassini Spots the Sombrero Galaxy from Saturn

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…

Only the Penitentes Shall Pass: Snow and Stars Near ESO’s ALMA

I just had to share this beautiful image by ESO photo ambassador Babak Tafreshi; it shows a star-filled night sky above the Chajnantor Plateau on the border of Chile and Bolivia, the site of the Atacama Large Millimeter/submillimeter Array (ALMA) observatory. The site, chosen for its remote location and incredibly clear, dry sky, is one of the best…

Hubble’s Stunning Star-Filled View of the Andromeda Galaxy

It’s Hubble’s 25th anniversary in space this year but it seems like we’re the ones getting all the presents! Yesterday NASA released two new high-def versions of the famous “Pillars of Creation” image, and now today there’s this: Hubble’s most detailed image ever of the Andromeda Galaxy! Containing over 100 million stars it’s not just the…

Hubble Gives Us Our Best View Yet Of The “Pillars of Creation”

NASA’s Hubble Space Telescope is celebrating the 25th anniversary of its launch this year and to commemorate the milestone it’s recently turned its gaze (during the course of about 15 orbits) back onto one of the most iconic targets of its career: the “Pillars of Creation,” five-light-year-high columns of cold gas in the process of being sculpted…

Titan: Dabbling in the Occult

Back in December of 2001, Saturn’s moon Titan passed in front of two background stars (called an “occultation”) from the point of view of the Hale Telescope at Palomar Observatory. Astronomers used the incredible resolving ability of the 5-meter telescope’s adaptive optics to watch the event, which revealed the diffraction of the stars’ light through…

Earth-Sized Alien Planet Found Around the Stars Next Door

These days it seems exoplanets are being discovered nearly every week, with “super-Earths”, “hot Jupiters” and “cold Neptunes” being identified (or at least announced as solid candidates) within star systems all around our neck of the galaxy. To top it all off, today the European Southern Observatory announced that an Earth-mass world has now been…

Orion Versus the Space Station

I captured the Space Station careening toward the Hunter on the night of March 2, 2012, just a little after 7:50 pm. A half-moon illuminated the event… who won? Well, let’s just say Orion’s still up there and the ISS faded away shortly after! (I’m sure they’ll be back for another go! They’re a plucky…
