Astronomers are turning to machines when it comes to learning more about the stars.
A NASA orbiter has spotted a long-lost Mars lander.
Scientists have discovered a star with three Earth-sized planets. Not only that, but one of the planets may just have temperatures that are moderate enough for liquid water, and possibly life, to exist.
The search for life on other planets continues. Now, scientists have discovered that exoplanets may be more likely to be hospitable to life and have liquid water than we thought.
Scientists have announced that the New Horizons spacecraft is entering the first of several approach phases that culminate on July 14 with the first ever close-up flyby of the dwarf planet.

In the past, scientists believed that chondrules on meteorites actually represented early kernels of terrestrial planets. Now, though, they've found that this is not the case.
The Chinese space program has hit a new milestone. A Chinese spacecraft service module has entered orbit around the moon.
Scientists have examined these biological effects a bit more closely and have found that in space, the shift of blood and fluid from the lower to the upper body caused by weightlessness is much higher and that blood pressure is much lower than previously thought.
NASA has officially released a spectacular image of one of the first solar flares of 2015. On Jan. 12, 2015, the sun emitted a mid-level solar flare that peaked at 11:24 EST.
