Starship Asterisk*

I have often thought of it as the "We're number 1" nebula

I'm flabbergasted about the fact that the clouds didn't move in 9 years between 2007 and 2016. That's really shaking up all knowledge about the Martian atmosphere, isn't it? See this animation where I put the map from the video over the 2007 Space Telescope surface map. mars_animate.gif I tend to a...

It would take a soundstage about the size of a football field that could be completely depressurized (or the regolith wouldn't behave properly). The actors would still need the pressure suits and you would need to use cameras with about 60-90 fps film speed. Definitely doable though the soundstage w...

At first glance, it looked like he was reaching into a cooler for a beer... Drinking and driving on the moon for the first time... Seriously tho. Getting lost on the moon would be a serious problem. What did they use to navigate? Some sort of inertial navigation system or radio beacons? After you a...

I would say the Hubble is a fantastic camera with the world's best telescopic lens

Now where did I put my car keys

Looking for tomorrow

If you zoom in to the 12:30 position there Is the appearance of a Double star (Brighter on top). Just below this appears to be a Screaming Specter ala Edvard Munch though this scream is having a bright idea

It is often stated, If you are looking for life, follow the water. If our next mission is to look for signs of life, perhaps this place should be a major candidate for a future mission landing site

However, for a good view of Saturn's rings one really needs to be on a high inclination satellite like Siarnaq or Albiorix. Thanks for the interesting data on these two moons. It appears that these little guys are not tidally locked. For the scenario I imagined to arise, one would have to have a la...

Perhaps we'll be fortunate enough for Juno to have a ringside seat for the next Jovian Impactor

They should tar to make use of that useless gas to produce electricity

Hey Curiosity...Nice Selfie

Could this be THE picture of an elusive Giant Squid? Spotted on Google Earth Images at coordinates 63d02'56.35"S 60d57'34.67"W http://cdn.images.express.co.uk/img/dynamic/80/590x/secondary/Giant-Squid-566296.jpg http://www.express.co.uk/news/weird/680025/LIVING-DINOSAUR-Shocking-sea-monste...

Here are some great images of the Paris Flooding with comparisons to the 1910 flooding event http://api.ning.com/files/xoNf2AGBkl*JdgLntgR-97VouV1UJBiUL5YxpYjUzQwcoRunE0xFmIRsF7O372sjzvgBxfP2vn72iCcTxoIGzACt4jSzm5on/191020163.jpg http://www.mymodernmet.com/profiles/blogs/julien-knez-paris-flooding-t...

With the GAP being placed at approx. 1AU then the 2 concentric rings appear to be at distances equal to Jupiter and Saturn

Hopefully the announcement is worth the wait and not just a redux of the Feb 11 APOD

If you turn the image 90 deg you get to view one of the ancient astronauts

Amazing, the internet rumors are absolutely true, Mars IS as big as Saturn in the night sky. ...or was that the full moon

And my mistake was in not considering the effect of Mars' gravity causing an increase in speed prior to the Orbital Insertion Burn

Got it. Mars is traveling through space at a little over 24KPS. So when the MGS arrived at a speed of 5KPS, while it was traveling significantly slower than Mars' solar orbit, it was traveling faster than Mars escape velocity and as such needed to reduce speed to 4KPS to ensure orbital insertion. S...
