Rogelio Bernal Andreo (born 9 January 1969) is a Spanish-American astrophotographer. He is known for his photographs of deep sky objects.
The spectrum of the Sun's solar radiation is close to that of a black body with a temperature of about 5,800 K. The Sun emits EM radiation across most of the electromagnetic spectrum. Multiple videos of the Chelyabinsk superbolide, particularly from dashboard cameras and traffic cameras which are ubiquitous in Russia, helped to establish the meteor's provenance as an Apollo asteroid. The first radio pulsar "CP 1919" (now known as PSR B1919+21), with a pulse period of 1.337 seconds and a pulse width of 0.04-second, was discovered in 1967. The following 146 pages are in this category, out of 146 total. This list may not reflect recent changes (learn more). Roadster photographed with a 0.43 m telescope of Dubbo Observatory in Australia, on 8 February 2018, 16:29–16:50 UTC, at a distance of 550,000 km (1.4 Lunar distances) from Earth.
On 6 February, an ejection of xenon propellant was commanded for attitude control to improve communication. The spin axis change rate was about two degrees per day.

The Dark Complex: The Dark Complex builds on the brilliant puzzle work of the first game, The Dark Room, by creating an entire complex of rooms, each with its own unique puzzle inside. When combining these measurements of stars' proper motions and their radial velocities, along with careful modeling, it is possible to obtain a picture of the rotation of the Milky Way disc.

When combining these measurements of stars' proper motions and their radial velocities, along with careful modeling, it is possible to obtain a picture of the rotation of the Milky Way disc. In triggered star formation, one of several events might occur to compress a molecular cloud and initiate its gravitational collapse. The merger of two stars would create a single more massive star, potentially with a mass larger than that of stars at the main-sequence turn-off point. The term originates from the planet-like round shape of these nebulae observed by astronomers through early telescopes. The first usage may have occurred during the 1780s with the English astronomer William Herschel who described these…
A Matter of Taste [1:10 min, 22.53 MB, download] Rogelio Bernal Andreo (born 9 January 1969) is a Spanish-American astrophotographer. He is known for his photographs of deep sky objects. These systems contain a total of 63 stars, of which 50 are red dwarfs, by far the most common type of star in the Milky Way. The mass of a star can be directly determined only from its gravitational attraction. Apart from the Sun and stars which act as gravitational lenses, this can be done only in binary and multiple star systems, making the binary stars an… In 1920, Arthur Eddington, on the basis of the precise measurements of atomic masses by F.W. Aston and a preliminary suggestion by Jean Perrin, proposed that stars obtained their energy from nuclear fusion of hydrogen to form helium and… Each of these smaller groups must also be hierarchical, which means that they must be divided into smaller subgroups which themselves are hierarchical, and so on. Each level of the hierarchy can be treated as a two-body problem by…
A little fun game where a spaceship flies around planets of the Solar System and its path is affected by planets' gravity. - TerryTsao/PlanetHopper
