Astronomers measured the velocity of 6,804 stars in seven dwarf satellite galaxies of the Milky Way. They found that, contrary to what Newton's law of gravity predicts, stars in these galaxies do not move slower the farther they are from their galaxy's core.

This is consistent with the fact that it is late southern summer and this region has been in sunlight for about 40 years.

The discovery offers evidence that Neptune, much like its big cousin Jupiter, hosts thick clouds of Trojans in its orbit, and that these asteroids probably share a common source. It also brings the total of known Neptune Trojans to four.

According to a new model for the capture of planetary satellites, Triton was originally a member of a binary pair of objects orbiting the Sun before it was captured by Neptune in a three-body gravitational encounter.

The images have been assembled into a time-lapse movie revealing the orbital motion of the satellites.

This vision of the future is the focus of a 12-month planning study conducted by a diverse team of experts led by Boeing Satellite Systems and funded by NASA.

This might sound like an oxymoron because Neptune is the farthest and coldest of the major planets. But NASA Hubble Space Telescope observations are revealing an increase in Neptune's brightness in the southern hemisphere, which is considered a harbinger of seasonal change, say astronomers.

If you made a large enough batch of these mixed gases, you might get the planet Neptune.
