Re: diameter of light echo
Shouldn't the diameter be twelve light years? The light will have traveled six light years in each direction from the star since six years ago. Unless the picture is three years old - it doesn't say - but it usually says the picture is old when that's the case. Actually diameter isn't even the &quo...

The Bible is not a science book but is a book of faith written by humans inspired by God - yet the writers are still processing data through their free-willed human minds. Little of what is mentioned in the Bible can be proven and there are more questions than answers regarding timelines of events ...

Re: Venus & Jupiter
Star of Bethlehem? I'm not buying into the planetary alignment perceived as "a new star". When the writer wrote about "a new star", the schooled travelers saw something that wasn't there before, like a comet or a (super)nova. With planets, one can see them getting closer to each...

Imagine aligning an image with, say, 500 meters per pixel resolution with a similar image from years gone by and blinking back and forth to see if there have been changes.

Re: Asteroids striking the moon
How large would an asteroid striking the moon have to be to actually disturb its orbit? If TU24 had impacted the moon on either its leading or trailing end it could changed its orbital speed (of ~ 1 km/s) by enough to have changed its orbital major axis (of ~ 770,000 km) by about 1 centimeter. This...

First, the Hubble telescope. It was a success after its mirror was fixed, at an extra cost to the taxpayer of several hundred million dollars.

Re: Get rid of NASA
Guys, NASA isn't the only government-funded agency capable of doing the highest quality research that can produce equally valuable spin-offs, and much more cheaply at that. That's right! The internet, for instance, was an unintended spin-off of high energy particle physics - an even more esoteric w...

Re: NASA desperate for a future
NASA desperately wants to send astronauts to Mars. It's obvious to anyone with the slightest common sense that there is nothing an astronaut can do on Mars that a robot can't do as well and much, much more cheaply. Similarly for Moon exploration. Mars is simply a dead desert. The only planet that n...
