radio telescope by penticton
My visit to radio telescope by Penticton, BC. Canada.

Below are bookmarks to some eyes
on the universe arranged pretty much by
what they are looking at.

Observatories and labs

Accelerator lab probing cosmic questions in physics, medical research also.  Located near UBC Campus in Vancouver, BC Canada.  I toured Triumf in 1989.

National accelerator lab in USA.  Explores cosmic questions of physics.  Located near Chicago, IL.

Stanford Linear Accelerator
Now re purposed as an Xray microscope.  Looking deep into molecules, exploring photosynthesis and so forth.

Gravity Wave Detectors

Multi site gravity wave detector.  Hanford, Washington. Livingston, Louisiana.

Virgo Gravity Wave Detector, ESA in Italy
Similar to Ligo, in USA.  If all 3 (now 4 counting the new one in Japan) operate simultaneously astronomers can use triangulation to tell where in the sky the gravity wave comes from.

Japanese Gravity Wave Detector.

Radio and Microwave Astronomy

Atacama Large Millimeter and Sub Millimeter Array.  Largest astronomical project  in world, so they say.  Over 60 radio telescope dishes coordinated to act as one with high resolution.  Located on a high plain in the Atacama Desert of northern Chile.  Built by European Space Agency and international cooperation including the nation of Chile.

Radio antenna dish built into bowl shaped valley in Puerto Rico.  World's 2nd largest radio dish after FAST in China. Telescope has been decommissioned and the suspended platform has collapsed into the dish below. I think, maybe, they can restore the dish below. Do they need a suspended platform? Maybe they could use drones to hold antennas in the focus of the dish?

Astronomy Satellites

A global space astrometry mission, Gaia is making the largest, most precise three-dimensional map of our Galaxy by surveying more than a thousand million stars.  Gaia will monitor each of its target stars about 70 times over a five-year period. It will precisely chart their positions, distances, movements, and changes in brightness. It is expected to discover hundreds of thousands of new celestial objects, such as extra-solar planets and brown dwarfs, and observe hundreds of thousands of asteroids within our own Solar System. The mission will also study about 500 000 distant quasars and will provide stringent new tests of Albert Einstein’s General Theory of Relativity.

Constellation of 6 micro satellites to study slight variations in the brightness of nearby and bright stars.  Stellar seismology.  Canada and several other countries participating.  Launched Feb. 25 2013.

Xray  Telescope.  Launched June 13 2012 by rocket from a plane.  NuSTAR uses a unique set of eyes to see the highest energy X-ray light from the cosmos. The observatory can see through gas and dust to reveal black holes lurking in our Milky Way galaxy, as well as those hidden in the hearts of faraway galaxies.

High Energy Transient Explorer
Lies in wait for mysterious gamma ray bursts that suddenly cause the universe to flash, like someone just took a picture.  Tries to pinpoint where burst originated so other astronomers can look to see what is there.  Something must be causing those huge explosions; two neutron stars colliding? a super super nova?

Studies gamma ray bursts with three telescopes to get data from across a broad range of the electromagnetic spectrum. 

Sometimes called the Humble Space Telescope.  Lots of bang for the buck.  A Canadian project, from UBC in Vancouver.  More sophisticated look at variations in stellar brightness.  Should be launched in late 2002.  Looks like a suitcase.

Galileo Jupiter Mission
Orbited Jupiter.  Exploring planet and its many moons.  Mission had been extended several times.  Nearing end of its stabilizing propellant, plans called for crashing it into Jupiter, right before craft dies, so it doesn't contaminate Jupiter's moon Europa where life may exist.  Fantastic photos of Jupiter and its many moons, from up close, including the volcanoes on Io.

Exploring the Sun

Genesis Mission
Sample solar wind, bring back to Earth 2004.

Launched in 1990.  Looked down (if there is such a thing as down out there) on the poles of the sun.  While other satellites are in plane with sun's equator, Ulysses is only one to orbit over north and south poles of sun.   From this vantage point, it had a unique perspective.  Lasted far past it's primary mission, but finally had to be turned off in June 09 as power was running low.
