Flocculent spiral NGC 2841

by Paul Adamson February 17, 2011
The galaxy NGC 2841 – shown here in this NASA/ESA Hubble Space Telescope image, taken with the space observatory’s newest instrument, the Wide Field Camera 3 – currently has a relatively low star formation rate compared to other spirals. It is one of several nearby galaxies that have been specifically chosen for a new study […]

Messier 78

by Paul Adamson February 16, 2011
The nebula Messier 78 takes centre stage in this image taken with the Wide Field Imager on the MPG/ESO 2.2-metre telescope at the La Silla Observatory in Chile, while the stars powering the bright display take a backseat. The brilliant starlight ricochets off dust particles in the nebula, illuminating it with scattered blue light. Igor […]

VISTA Reveals the Secret of the Unicorn

by Paul Adamson October 6, 2010
The VISTA (Visible and Infrared Survey Telescope for Astronomy) is a 4.1-metre wide-field telescope at the Paranal Observatory in Chile and is run by the European Southern Observatory. In this zoom sequence we start with a broad panorama of the Milky Way, including the familiar constellation of Orion. As we close in on part of […]

Zooming Into Sun-Like Star HD 10180

by Paul Adamson August 24, 2010
The European Southern Observatory (ESO) using the High Accuracy Radial velocity Planet Searcher (HARPS) instrument have discovered a planetary system containing between five to seven planets orbiting the Sun-like star HD 10180. Five of the planets are approximately the size of Neptune, which is about 17 times the mass of Earth. All five of the […]

Volcanic ash on Mars

by Paul Adamson May 14, 2010
The European Space Agency (ESA) has taken a picture of the Meridiani Planum on Mars using the Mars Express High Resolution Stereo Camera. To orient yourself, remember that North in this image is to your right. Therefore, looking at the volcanic crater, you can see that the prevailing winds are from the North-East, and are […]

Herschel reveals the hidden side of star birth

by Paul Adamson May 7, 2010
The Herschel Space Observatory is an infrared telescope run by the European Space Agency (ESA). It is named for Sir William Herschel who discovered the planet Uranus and the infrared spectrum. The primary mirror for Herschel Space Observatory is 3.5 meters wide, making . The ESA has released new images of star formation clouds in […]

Hubble celebrates its 20th birthday

by Paul Adamson April 23, 2010
The Carina Nebula, also known as NGC 3372, is an Emission Nebula in the Milky Way. This nebula is four times larger than the Orion nebula. It is located between between 6,500 and 10,000 light years from Earth. However, it is found in the night skies of the southern hemisphere. The Hubble Telescope’s 423 million […]

3-D view of Phobos

by Paul Adamson March 15, 2010
Recently we told you about the Mars Express flyby of the Mars moon Phobos that occurred on March 7. Now it is time to break out the old-time red/cyan glasses to see some spectacular views of the moon in 3-D. They have also released high resolution images of Phobos with every pixel equal to just […]

Visualizing the Mars Express flyby of Phobos

by Paul Adamson March 4, 2010
The Mars Express is a spacecraft that has been in orbit around Mars since 2004. Yesterday it conducted a fly-by of the Phobos, the larger of the two moons of Mars. As it passed by the moon, the gravity of the moon deflected the orbit of the Mars Express. From this deflection, scientists can calculate […]
