As people on Earth celebrate the holidays and prepare to ring in the New Year, an ESA/NASA spacecraft has quietly reached its own milestone: on December 26, the Solar and Heliospheric Observatory (SOHO) discovered its 2000th comet. Drawing on help from citizen scientists around the world, SOHO has become the single greatest comet finder of all time. This is all the more impressive since SOHO was not specifically designed to find comets, but to monitor the sun. "Since it launched on December...

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. SOHO's record-breaking discovery was made late on 25 June. When it comes to comet catching, the SOlar and Heliospheric Observatory has one big advantage over everybody else: its location. Situated between the Sun and Earth, it has a privileged view of a region of...

A medical X-ray technique has been adapted to produce the first detailed map of the structure of the Sun's outermost layer, the corona, created from direct observations. The results will be presented by Dr Huw Morgan at the RAS National Astronomy Meeting in Belfast on Tuesday 1st April.Tomography, a technique with multiple medical applications including CAT scans, uses a series of images taken from many different angles to reconstruct a 3-dimensional map of a patient's body. "This is a...

If you watch the morning or evening sky these days and have a clear view of the horizon, you will be able to spot a bright object with a prominent tail. Instructions for viewing the comet in the morning from Spaceweather.com: At dawn, go outside and face east Using binoculars, scan the horizon The comet is located just south of due east Instructions for viewing the comet in the evening from Spaceweather.com: At sunset, go outside and face west Using binoculars, scan the horizon The comet is...

NASA -- One thousand comets have been discovered to date using the Solar and Heliospheric Observatory (SOHO) spacecraft. The SOHO spacecraft, a joint effort between NASA and the European Space Agency, has accounted for approximately one-half of all comet discoveries with computed orbits in the history of astronomy. Many SOHO comet discoveries have been by amateurs using SOHO images on the internet, and SOHO comet hunters come from all over the world. Toni Scarmato, a high school teacher from...

ESA -- As of July 6, 2005, 989 comets have been discovered using the ESA/NASA Solar and Heliospheric Observatory (SOHO) spacecraft, which is expected to discover its 1000th comet this summer. The SOHO spacecraft, a joint effort between NASA and the European Space Agency, has been so prolific that it has accounted for almost half of all comet discoveries for which orbits have been computed in the history of astronomy. Before SOHO was launched, only 16 "Ëœsungrazing'...


Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
