The Whale and the Hockey Stick

Last night marked Jupiter’s “opposition” – this is the time of year where Jupiter is at its closest point to Earth, and it’s at its biggest and brightest. By a stroke of luck, we had unusually clear skies for this event, and its moon Io was also crossing in front of Jupiter! You can see…

Deep-sky astrophotography is the ultimate hobby for nerds; it combines endless tinkering with highly specialized technology, exploration of the cosmos, and constant challenges, achievements, and learning. But, could this hobby be automated to the point where anyone can do it? Products such as Stellina and Unistellar promise to deliver an experience where you can plop…

This image really blows my mind – this is the reflection nebula NGC1333 in Perseus. The blue part is reflected gas and dust from the star that’s lighting up – that’s nothing too unusual. But check out the little red blobs above it. Many of those are “Herbig-Haro” objects, formed by jets spewing out from…

I’ve imaged this one before, but I keep coming back to it because I just can’t believe its golden color is real. But even after applying all I’ve learned about color calibration – I can say pretty definitely that these are its true colors. It’s also benefited from advances in image processing software, making the…

Well, it was certainly born of fire. This is planetary nebula Abell 39, one of the largest spheres in the galaxy… it’s 2.6 light-years across! It really is that color blue. You’re seeing ionized Oxygen gas blown off by the dying star in its center. Look closely for the distant galaxies in the background, including…

Three nearby galaxies: M65, M66, and NGC 3628. All three are spiral galaxies, viewed from different angles. You can guess which one is called the “Hamburger Galaxy” 🙂
