ESO`s VLT Helps ESA`s Rosetta Spacecraft Prepare to Ride on a Cosmic Bullet
New Images of Comet Wirtanen`s Nucleus New images of Comet Wirtanen`s 1-km `dirty snowball` nucleus have been obtained with the ESO Very Large Telescope at Paranal (Chile). They show this object at a distance of approx. 435 million km from the Sun, about the same as when the Rosetta spacecraft of the European Space Agency (ESA) arrives in 2011.... view more...

ESA's Rosetta mission: A status report
Following the decision not to launch Europe's comet chaser Rosetta in January, scientists and engineers in the programme have been examining several alternative mission scenarios. Each has been looked at on the basis of the expected scientific return, the technical risks related to using the Rosetta design in the new mission, and the containment... view more... (2003-03-21)
Top class images help ESA`s Rosetta prepare to ride on a cosmic bullet
Chase a fast-moving comet, land on it and `ride` it while it speeds up towards the Sun: not the script of a science-fiction movie, but the very real task of ESA`s Rosetta spacecraft. New observations with the European Southern Observatory`s (ESO) Very Large Telescope (VLT) provide vital information about Comet Wirtanen - Rosetta`s target - to... view more... (2002-02-26)
SOHO`s private view of a sunbathing comet
You could see it easily with your unaided eye (but don`t try!) if only Comet Machholz 1 were not so very close to the Sun. This unusual comet, reputed to flare up a lot, is today sweltering only 18 million kilometres from the Sun. This is its closest approach on an orbit that brings it back to the solar vicinity every 63 months. The best and... view more... (2002-01-09)
Rosetta bound for outer Solar System after final Earth swingby
This morning, mission controllers confirmed that ESA's comet chaser Rosetta had swung by Earth at 8:45 CET as planned, skimming past our planet to pick up a gravitational boost for an epic journey to rendezvous with comet 67P/Churyumov-Gerasimenko in 2014. view more (2009-11-16)
Naked eye comet shines on UK National Astronomy Meeting
Naked eye comets are generally few and far between, so UK astronomers have been surprised and delighted by the appearance of comet C/2002 C1 (Ikeya-Zhang) in the night sky. Scientists are particularly intrigued by the re-appearance of Ikeya-Zhang after a long exile in the depths of the outer Solar System. According to Mark Bailey (Armagh... view more... (2002-04-04)
Comet probes reveal evidence of origin of life, scientists claim
Recent probes inside comets show it is overwhelmingly likely that life began in space, according to a new paper by Cardiff University scientists. view more (2007-08-15)
SSTL momentum wheel aids Rosetta mission’s 9-year journey into space
Guildford, UK SSTL have delivered two flight standard momentum wheels to DLR in Germany, one of which will fly on the Rosetta spacecraft that is due to be launched in January 2003, the other as a flight spare. The Rosetta spacecraft will rendezvous with the comet "46 P/Wirtanen" on 29th November 2011 as it makes one of its periodic visits to the... view more... (2001-04-10)
Guess when a comet will be spotted to win a SOLARMAX DVD
ESA`s solar satellite, SOHO, has become the best comet spotter the world has ever known. When SOHO`s latest solar images are posted on the Internet, astronomers and space enthusiasts alike are thrilled when they spot evidence of new comets that have never been seen before as they pass close to the Sun. Since SOHO`s launch in 1995, 435 new comets... view more... (2002-05-10)
New comet discovered in Canada
Rob Cardinal was looking for an asteroid, but ended up finding a comet. It is the first time a comet has been discovered at the University of Calgary's Rothney Astrophysical Observatory, which is located about 35 kilometres southwest of Calgary, and only the second Canadian discovery of a comet using a Canadian telescope in nearly a decade. view more (2008-10-15)
Follow Rosetta's final Earth boost
ESA's comet chaser Rosetta will swing by Earth for the last time on 13 November to pick up energy and begin the final leg of its 10-year journey to comet 67P/Churyumov-Gerasimenko. ESA's European Space Operations Centre will host a media briefing on that day. view more (2009-11-05)
ESC Spokespersons react to COMET results presented today at Heart Failure / ISHR-ES 2003
Monday 23 June, Strasbourg, France: The COMET, The Carvedilol or Metoprolol European Trial, results were presented a Hot Line Session this morning at Heart Failure / ISHR-ES 2003, the meeting of the European Society of Cardiology's Working Group on Heart Failure, held jointly this year with the Annual Congress of the European Section of the... view more...

SOHO discovers its 1500th comet
The ESA/NASA SOHO spacecraft has just discovered its 1500th comet, making it more successful than all other comet discoverers throughout history put together. Not bad for a spacecraft that was designed as a solar physics mission. view more (2008-06-30)
Comet dust brought back to Earth: paving the way for Rosetta
Scientists around the world eagerly await the arrival of sample particles from Comet Wild 2, which are being brought back to Earth by the US Stardust spacecraft on 15 January this year. view more (2006-01-13)
Evidence for more dust than ice in comets
Observations of Comet 9P/Tempel 1 made by ESA's Rosetta spacecraft after the Deep Impact collision suggest that comets are 'icy dirtballs', rather than 'dirty snowballs' as previously believed. view more (2005-10-14)
ESA`s shortcut to a comet
Night owls across Europe, get ready. On the night of 18-19 November 2002, you may see a spectacular sky show. As tiny particles in Comet 55/P Tempel-Tuttle`s tail enter Earth`s atmosphere, they will pierce through it, heating up, and finally explode. Welcome to one of the most spectacular natural fireworks displays of the year: a meteor shower... view more... (2002-11-15)
NASA satellite sees solar hurricane detach comet tail
A NASA satellite has captured the first images of a collision between a comet and a solar hurricane. It is the first time scientists have witnessed such an event on another cosmic body. view more (2007-10-02)
Hubble zooms in on heart of mystery comet

MU Scientist Discovers 'Firework' Display in Helix Nebula
A star does not die without getting noticed and may even leave the universe with "fireworks." At the end of its life cycle, a star begins to collapse in the middle and throws new material into space. view more (2009-07-21)
COMET results released at Heart Failure / ISHR-ES 2003 support superiority of carvedilol in the treatment of chronic heart failure in major European trial
Monday 23 June 2003, Strasbourg, France: According to results presented today at the Heart Failure / ISHR-ES 2003, the non-selective beta blocking agent carvedilol is more effective in the treatment of patients with chronic heart failure than the '¢-1 selective beta blocker metoprolol. These results were presented at this morning's Hot Line... view more... (2003-06-23)
