Good Boy! is a 2003 American science fiction comedy film directed by John Hoffman, based on the book Dogs from Outer Space by Zeke Richardson; Hoffman and Richardson collaborated on the screen story, while Hoffman wrote the screenplay.
Extraterrestrial life, or alien life ... Based on observations from the Hubble Space Telescope, there are nearly 2 trillion galaxies in the observable universe. [39]
Hubble was launched in 1990, but its main mirror had been ground incorrectly, resulting in spherical aberration that compromised the telescope's capabilities. The optics were corrected to their intended quality by a servicing mission in 1993. Hubble is the only telescope designed to be maintained in space by astronauts.
Edwin Powell Hubble (November 20, 1889 – September 28, 1953) [1] was an American astronomer. He played a crucial role in establishing the fields of extragalactic astronomy and observational cosmology.
NASA is changing the way the Hubble Space Telescope operates to bypass an issue that keeps putting the space observatory into “safe mode” shutting down its work. The storied Hubble telescope ...
Philip Cary Plait (born September 30, 1964), [1] also known as The Bad Astronomer, is an American astronomer, skeptic, and popular science blogger. Plait has worked as part of the Hubble Space Telescope team, images and spectra of astronomical objects, as well as engaging in public outreach advocacy for NASA missions.
The team nicknamed the star system Mothra due to its extreme magnification and brightness. Surprisingly, Mothra has appeared before, detected in Hubble observations nine years ago.
H 0 is Hubble's constant and corresponds to the value of H (often termed the Hubble parameter which is a value that is time dependent and which can be expressed in terms of the scale factor) in the Friedmann equations taken at the time of observation denoted by the subscript 0. This value is the same throughout the universe for a given comoving ...
