Here is my local Telescope just a 30min drive up the mountain. It has a large big sceen
projection screen of what they are looking at when you arrive.
The Hale Telescope at Mt. Palomar in California was the largest telescope in the world from 1948 to 1974. Today, each of the twin 10-meter Keck telescopes atop Mauna Kea in Hawaii are twice its size.
Discovery's of at Palomar Mountain include:
1985 – 2000 Second Palomar Observatory Sky Survey
POSS II encompasses 897 survey quality plates in each of 3 colors.
Forms the basis for the digital survey (DPOSS), the second HST GSC, and the USNO astrometric and photometric catalogs, all of which contain over 1 billion stars and over 50 million galaxies
More than hundred supernovae discovered.
Dozens of comets and asteroids discovered.
The digitized version of the sky survey has been used in many fields of astronomical research including finding over 100 high red shift (very distant) quasars (a record number until very recently) and about 20,000 clusters of galaxies - the largest such catalog ever.
1986 Telescope Renamed as Samuel Oschin Telescope
Samuel Oschin Family Foundation awards grant to Caltech’s Palomar Observatory
Funds used for POSS II, adaptive optics on the 200-inch telescope, new CCD cameras, and more
2001 Samuel Oschin Telescope Automation
Original photographic camera replaced with a new 3-CCD electronic camera.
Telescope control system automated to enable automatic operation.
Upgrades enable continuous, automatic survey of sky for moving objects (asteroids, comets), variable stars and transient objects (supernovae, gamma-ray bursts).
2001- 2003 Near Earth Asteroid Tracker (NEAT) Survey
JPL’s NEAT survey discovered 189 near-earth asteroids and 20 comets
2002 Quaoar Discovered
Quaoar is a frozen world located in what is known as the Kuiper Belt
At 800 miles in diameter Quaoar is the largest object found in our solar system since the planet Pluto was discovered in 1930.
Gamma-Ray Burst Observations
- October 4, 2002
- An image was obtained by the Samuel Oschin Telescope with the NEAT camera just 9 minutes after the burst was detected by satellite.
- Astronomers world-wide were notified of the event within 3 hours.
- The most interesting science was the slow early-time decay, which may be due to on-going activity of a black hole central engine. December 11, 2002
- Image of a gamma-ray burst 20 minutes after the burst. Announcement to the world less than an hour after the burst.
- The most interesting science was the demonstration that the burst, although faint, was not "dark" -- that is, the faintness of the burst was not due to absorption by gas and dust in its host galaxy.
2003 New QUEST Camera installed
Yale University’s 112-CCD, 161-megapixel camera, one of the world’s largest.
JPL’s NEAT Survey continues with QUEST camera.
Additional
survey work continues with searches for variable stars, quasars, gravitational lenses and distant supernovae.
February, 2004 Orcus (2004 DW)
Discovered
2004 DW is another Kuiper Belt object.
It is even larger than Quaoar, possibly 1,000 miles across.
It orbits the Sun at a distance 42 times greater than Earth’s, about every 250 years.
November, 2003 Sedna (2003 VB12) Discovered
Most distant known object to orbit the Sun (10,500 year orbit)
Possibly as large as 1,100 miles in diameter
July, 2005 Dwarf Planet Eris (2003
UB313)
Discovery Announced
Orbits the Sun with a 560 year period
Larger than Pluto, ~2,400 km in diameter
November, 2006 The Big Picture
Unveiled at Griffith Observatory
Largest astronomical photograph ever produced
152 feet wide and 20 feet high
