  3. stoneriree said: How do you make a time lapse gif of the sky at night

    take a series of long exposure shots at a set time interval. play the frames in sequence. the length of exposure will drastically change how your time lapse looks. if u want cloud motion- use no more than 3-6 seconds exposure time. if you want star motion, go longer like maybe 20 seconds of exposure. for best results- you will need a decent DSLR with an intervelometer and a tripod. or just something you can take long exposure shots every couple seconds easily. really you just need a point and shoot and a timer for the minimum. things to remember- stabilization make sure your camera is stable, because stabilizing footage frame by frame sucks a lot. planes- the longer your exposure time, the longer the plane light trails will be, varying the look of your lapse.

An invisible force at the center of our galaxy
Scientists have theorized that our Milky Way galaxy has a super massive black hole at the center of it, but how did this idea come about?  How do astronomers measure something that has actually never been seen in our telescopes?
Above is an animation of star movements in our galaxy over the past 16 years.  They all orbit around a point that emits no light in our galaxy.  We can measure the mass of these stars and calculate that their orbits require an object with the mass of 4 million Suns.  So far this points to a super massive black hole in our galaxy.

Showing the terminator on the lunar farside. The peaked crater at left is Tsiolkovskiy, again.
No date and time information attached to these images, but presumably just after escape from lunar orbit at midnight on the 16th.
