All through history, humans have created and shared stories that ponder the creation of stars — what they are and how the first stars came to be. Now, with new results from the Hydrogen Epoch of Reion...
Green Bank Telescope Joins 'Breakthrough Listen' to Vastly Accelerate Search for Intelligent Life in the Universe
Green Bank Telescope Breakthrough Listen Vastly Accelerate Search Intelligent Life the Universe
2015/8/4
The National Science Foundation’s Green Bank Telescope (GBT) will join in the most powerful, comprehensive, and intensive scientific search ever for signs of intelligent life in the Universe. The inte...
The Apparent Host Galaxy of PKS 1413+135: Hubble Space Telescope,* ASCA, and Very Long Baseline Array ** Observations
HST ASCA
2014/12/26
PKS 1413+135 (z = 0.24671) is one of very few radio-loud active galactic nuclei (AGNs) with an apparent spiral host galaxy. Previous authors have attributed its nearly exponential infrared cutoff to h...
A Two Micron All Sky Survey view of the Sagittarius dwarf galaxy. II. Swope telescope spectroscopy of M giant stars in the dynamically cold Sagittarius tidal stream

We describe the Hubble Space Telescope (HST) Wide Field Camera 3 (WFC3) Early Re- lease Science (ERS) observations in the Great Observatories Origins Deep Survey (GOODS) South eld. The new WFC3 ERS d...
We present the highest redshift detections of resolved Ly emission, using Hubble Space Telescope/ACS F658N narrowband-imaging data taken in parallel with the Wide Field Camera 3 Early Release Science...
Hubble Space Telescope Pixel Analysis of the Interacting Face-on Spiral Galaxy NGC 5194 (M51A)
Hubble Space Telescope Pixel Analysis Interacting Face-on Spiral Galaxy NGC 5194 (M51A)
2011/10/19
A pixel analysis is carried out on the interacting face-on spiral galaxy NGC 5194 (M51A), using the HST/ACS images in the F435W, F555W and F814W (BVI) bands. After 4x4 binning of the HST/ACS images to...
