Observational astronomy is a division of astronomy that is concerned with recording data about the observable universe, in contrast with theoretical astronomy, which is mainly concerned with calculating the measurable implications of physical models. It is the practice and study of observing celestial objects with the use of telescopes and other astronomical instruments.
Galileo Galilei turned a telescope to the heavens and recorded what he saw. Since that time, observational astronomy has made steady advances with each improvement in a variety astronomical instruments and related methods. — Wikipedia

R Coronae Borealis Awakes and Pluto Blocks a Star
by Bob King on August 8, 2018 at 2:49 pm
Sometimes, it's just as exciting to watch a celestial object fade or disappear as it is to see it explode. We celebrate the "return" of a mysterious variable star and prepare for Pluto to occult a star. The post R Coronae Borealis Awakes and Pluto Blocks a Star appeared first on Sky & Telescope. […]

Superflares from young red dwarf stars imperil...
on October 18, 2018 at 6:12 pm
Flares from the youngest red dwarfs surveyed are 100 to 1,000 times more energetic than when the stars are older. This younger age is when terrestrial planets are forming around their stars. […]
Astronomers find a cosmic Titan in the early...
on October 17, 2018 at 3:10 pm
Astronomers have discovered a titanic structure in the early universe, just two billion years after the Big Bang. This galaxy proto-supercluster, nicknamed Hyperion, is the largest and most massive structure yet found at such a remote time and distance. […]

on October 16, 2018 at 5:20 pm
According to new research, an object named GRB150101B -- first reported as a gamma-ray burst in 2015 -- shares remarkable similarities with GW170817, the neutron star merger discovered by LIGO and observed by multiple light-gathering telescopes in 2017. The new analysis suggests that these two separate objects may in fact be directly related. […]

Astronomers have nearly doubled the known number of 'fast radio bursts'-- powerful flashes of radio waves from deep space. The team's discoveries include the closest and brightest fast radio bursts ever detected and they have proved that fast radio bursts are coming from the other side of the Universe rather than from our own galactic neighborhood.

on October 22, 2018 at 1:00 pm
European astronomers have conducted a chemical study of the star HD 87240, a member of the open cluster NGC 3114. The new research, which determined the abundances of several elements in HD 87240's atmosphere, suggests that the object is a chemically peculiar star showcasing an overabundance of heavy elements. The finding is reported in a paper published October 10 on arXiv.org. […]
How mission delays hurt young astronomers
on October 22, 2018 at 12:45 pm
Back in Ye Olden Times, the job of astronomer was a pretty exclusive club. Either you needed to be so rich and so bored that you could design, build, and operate your own private observatory, or you needed to have a rich and bored friend who could finance your cosmic curiosity for you. By contrast, today's modern observatories are much more democratic, offering of a wealth of juicy scientific info for researchers across the globe. But that ease of access comes with its own price: you don't get […]

A stellar mass black hole is a compact object with a mass greater than three solar masses. It is so dense and has such a powerful force of attraction that not even light can escape from it. They cannot be observed directly, but only via secondary effects—for instance, in the case of a black hole feeding on a companion star. In general, when matter falls onto a black hole it does so "quietly" by way of an accretion disc. However, there are periods when this infall is violent and bursts, […]
