Hubble Conquers Mystic Mountain

Hubble Conquers Mystic Mountain
Where is this mystical land? (NASA/ESA/HST). Sometimes, words are not enough to describe views of the universe when captured through the lens of the Hubble Space Telescope. This is one of those moments. Kicking off its 20th anniversary (yes, that super-sized telescope has been in space that long —...

Then Spitzer Imaged Baby Stars in the Orion Nebula…

Then Spitzer Imaged Baby Stars in the Orion Nebula…
The Orion Nebula's star-forming region (NASA). Firstly, apologies that it’s been over a month since last posting to Astroengine.com. Call it slacking off, call it a sabbatical, either way, it’s not good. I’ve actually prepared several half-finished articles, but I just never got around...

Warning, Over-Hyped Title Alert: But It’s A Frackin’ SUPERNOVA!

Warning, Over-Hyped Title Alert: But It’s A Frackin’ SUPERNOVA!
"SuperNova" by Shadow-Trance (DeviantArt) I’m not kidding, last week was a huge mess of a supernova doomsday circus. It was like whispering “there’s a bomb under your chair” to the person next to you in a crowded theater and then watching the resulting flood of people...

Whatever Happened to Hyper-Velocity Star HD 271791?

Whatever Happened to Hyper-Velocity Star HD 271791?
One scenario: Exploding star flings binary parter away at high velocity (Max Planck Institute for Astrophysics) HC 271791 is a star with a problem, it’s moving so fast through our galaxy that it will eventually escape from the Milky Way all together. However, there is a growing question mark hanging...

Life is Grim on the Galactic Rim

Life is Grim on the Galactic Rim
Babylon 5's White Star approaches the Shadow's homeworld of Z'ha'dum on the Galactic Rim. It would appear that scientists have confirmed that the outer edge of the Milky Way is a bad location for life to even think about existing. This research reminded me of the “Galactic Rim” in the 90′s...

Brown Dwarfs: “Over-Achieving Jupiters” not “Failed Stars”

Brown Dwarfs: “Over-Achieving Jupiters” not “Failed Stars”
Why is the term “failed star” synonymous with brown dwarfs? On the one hand, brown dwarfs lack the mass to sustain nuclear fusion in their cores. On the other hand, who said brown dwarfs were trying to be stars? Who ever said that becoming a star was the pinnacle of stellar living? Perhaps...

Are Brown Dwarfs More Common Than We Thought?

Are Brown Dwarfs More Common Than We Thought?
In 2007, a very rare event was observed from Earth by several observers. An object passed in front of a star located near the centre of the Milky Way, magnifying its light. Gravitational lensing is not uncommon in itself (the phenomenon was predicted by Einstein in 1915), but if we consider what facilitated...

WR 104: Not The Killer It Used To Be

WR 104: Not The Killer It Used To Be
WR 104. A killer? Not so much. It’s interesting how astronomical harbingers of doom have the ability to pop up more than once on the ‘net. However, the doom isn’t quite as terrifying when you’ve sat through a conference presentation by a scientist who has exhaustively given every...

Star Formation: The Game

Dave Mosher, I’m pointing my finger at you for this late night effort! Usually I stay up late to write articles, but for the last 30 minutes I’ve been playing this game after Dave sent a message on Twitter saying he had been playing a “simple” and “addictive” star...

What Will Happen When the Sun Turns into a White Dwarf?

Strong tidal interactions are thought to shred any asteroids or comets as they get too close to a white dwarf (NASA) All the way back in January, I had the great fortune to attend the American Astronomical Society’s (AAS) conference in Long Beach, California. I had a lot of fun. However, between...
