... GOODS unites extremely deep observations from NASA's Great Observatories, Spitzer , Hubble , and Chandra , ESA's Herschel and XMM-Newton , and from the most powerful ground-based facilities, to survey the distant universe to the faintest flux limits across the electromagnetic spectrum. ... The space-based observations are complemented by ground-based imaging and spectroscopy, including extensive commitments of ESO and NOAO observing time. ... 2010-04-10: Deep VLA 1.4 GHz data for GOODS-North . ...

The ESA/ESO Astronomy Exercise Series 2 . The Distance to Messier 100 as Determined by Cepheid Variable Stars . ... The small variations in distance to the individual Cepheid variable stars in the Cloud are negligible compared with the much larger distance to the SMC. ... In this way Cepheid variable stars can be used as one of the 'standard candles' in the Universe that act either as distance indicators themselves or can be used to calibrate (or set the zero point for) other distance indicators. ...

The Sun is our nearest star and the source of energy for life on Earth. ... For centuries astronomers wondered whether they were clouds floating in the Sun's atmosphere, but we now know that they really are huge regions of magnetic field, about as intense as the field at the poles of an iron magnet. ... Such abrupt events were named solar flares , and what made them especially interesting was that occasionally, after a prominent flare, a magnetic storm would erupt on Earth. ...

... The expansion is measured as a number called the Hubble Constant . ... Our value is about 20% lower than the one got with the Hubble Space Telescope in 1994," said Dr Jim Lovell, leader of the team that made the measurement. The Hubble Constant is named after American astronomer Edwin Hubble, who in the 1920s found that other galaxies were moving away from ours. ...

December 2006 Astronotes 1 Hubble sees Red! ... Hubble did the maths and discovered that M31 was very distant indeed (2.2 million light years away is the accepted figure today), so far in fact that it must be a galaxy in its own right. ... M31 Andromeda Galaxy A Hubble Space Telescope view of the galaxy's core is now called Hubble's Law, and it made his name. ... If you measure the redshift of a galaxy, you will know its velocity, and by Hubble's Law, you will automatically know its distance away. ...

Comet C/1999 S4 (LINEAR) was discovered on 27 September 1999 by the Massachusetts Institute of Technology/Lincoln Laboratory programme LINEAR (Lincoln Near Earth Asteroid Research), at the White Sands Missile Range in Socorro, New Mexico, USA. The LINEAR programme , which uses a 1m prime-focus Cassegrain telescope to search the sky for comets and asteroids passing close to the Earth, is funded by the United States Air Force. ...

... The Galactic low-mass X-ray binary GS 2023+338 was discovered during the burst on May 22, 1989 with the Japanise satellite Ginga (aka Galaxy). The flux reached 17 crabs (this unit of flux measurement is an bright X-ray source, Crab Nebula) at 10-35 keV. ... No other radio telescope worldwide carried out multi-frequency measurements. ... Upon 14 days the radio flux fell below the detection level at the RATAN-600 in relation to the decrease of the X-ray flux. ...

... 2016 March 23 . The Great Nebula in Carina . ... Eta Carinae , the most energetic star in the nebula, was one of the brightest stars in the sky in the 1830s, but then faded dramatically. Eta Carinae is the brightest star near the image center, just left of the Keyhole Nebula . While Eta Carinae itself maybe on the verge of a supernova explosion, X-ray images indicate that much of the Great Carina Nebula has been a veritable supernova factory . ... About APOD | ...

For centuries astronomers wondered whether they were clouds floating in the Sun's atmosphere, but we now know that they really are huge regions of magnetic field, about as intense as the field at the poles of an iron magnet. For some reason the field slows down the flow of heat from the Sun's interior and keeps sunspots slightly cooler than their surroundings. ... Solar Eclipses . ...
