Edwin Hubblewas a Rhodes Scholar at Oxford where he read Law & Spanish! .
Vital Statisticsas of last week!
6GMOS galaxy spectrum
• Cost $18,000,000,000 and counting• 9,169 refereed papers• 326,138 citations • 16,051 proposals submitted via the TAC• 4,302 approved for Cycles 1 - 18.• ~ 3,600 FTEs of effort at STScI
Scientifically HST has changed everything in
astronomy.

Prof. Danieli: `the most succesful enterprise in
contemporary science’
Brown et al.
Eris is ~5% larger and ~30% more
massive than Pluto
Eris & Dysnomia
Altered our view of the physical content of the
Solar System

The triple main sequence in NGC 2808
Overabundances of helium (Y~0.30, Y~0.40) can reproduce the two bluest main sequences
Piotto et al. 2007, ApJ, 661, L35 Astrometry!
Stellar populations and star formation history

14GMOS galaxy spectrum
• WPC-3 ultra-violet imaging capabilityFEEDBACK
Dark Matter
15GMOS galaxy spectrum
Gravitational lensing has proved to be a uniquely powerful method to probe the distribution of Dark Matter.Now we need a direct detection in the lab! (not HST’s problem)
Dark Energy
16GMOS galaxy spectrum
• HST will continue to be the primary tool for high z SNae probes of dark energy.
• Measuring H0 to ~ few % will tighten constraints on cosmological concordance.
• Measuring H0 to 1% could be revolutionary

COS has unique ultra-violet spectroscopic capability
The physical conditions and content of galaxy halos
18GMOS galaxy spectrum
No longer limited to a few l-o-s to bright QSOs, we can now look at different types of galaxies & make the connection with galaxy evolution – in/outflows & feedback!
The tomography of the cosmic web
19GMOS galaxy spectrum
No longer limited to a few l-o-s to bright QSOs, we can now look where there are interesting features
Wouldn’t John Huchra have been
excited by this prospect!
WFC3 grism capability
20GMOS galaxy spectrum
WFC-3 and the most distant galaxies
21GMOS galaxy spectrum
z = 7-8 galaxies WFC/IR vs. NICMOS
WFC-3 and the most distant galaxies
22GMOS galaxy spectrum
z= 7-8 galaxies are:• Small• Blue – no dust• α =1.7 - low mass galaxies dominate• some stars formed z>10
CANDELS & CLASH to come
Why has HST been sosuccessful?
23GMOS galaxy spectrum
Well obviously because it does great science!
Prof. Danieli: `the most successful enterprise in
contemporary science’
Why has HST been so successful?
24GMOS galaxy spectrum
HST accomplishments are more widely recognized among the public than:
Prof. Danieli: `the most successful enterprise in
contemporary science’
• the Human Genome project, • magnetic materials that make iPod’s possible,• cancer therapies
WHY?: there wasn’t a fortune to be made
Why has HST been so successful?
25GMOS galaxy spectrum
Funding : It has been funded at a level that has enabled new instruments, refurbishment of the telescope infrastructure, and exploitation of the data............ even theory!
Why has HST been so successful?
26GMOS galaxy spectrum
Great Pictures: Science as Art
Why has HST been so successful?
27GMOS galaxy spectrum
It is unique & we prize access to it.
Time allocation modes:Key projectsGTO time GO programmesSnapshots, ToOAllocations to small & large programmesTreasury programmesDirectors Discretionary Time Multi-Cycle Treasury programmes
Plus conflict ofinterest protocols
HST TAC is a exemplar of how to distribute a scarce and valuable resource
Why has HST been so successful?
28GMOS galaxy spectrum
It is unique and therefore used with almost every other facility.
Chandra + Newton XMMSpitzer + HerschelKeck, VLT, Gemini, Subaru etc.eVLA, VLBA, etc.JCMT, PbB, soon ALMACorot, Kepler
Why has HST been so successful?
29GMOS galaxy spectrum
There has been a HUGE effort at outreach &
education
Why has HST been so successful?
30GMOS galaxy spectrum
It has captured the imagination of the media and the public because it has been a human drama :
Challenger accidentSpherical aberrationCOSTAR Columbia accidentRefurbishment missions
The astronauts are brave pioneers
What do Bob Fosbury & HST have in common?
31GMOS galaxy spectrum
Hubble gives us a unique new
perspective on the Universe and our
place in it.
