In SOHO’s pictures, watch a comet passing near the Sun

18.04.2002


Between now and Saturday, 20 April, you can follow via the Internet the progress of the new-found Comet SOHO-422. Usually, comets seen by the SOHO spacecraft quickly burn up in the Sun’s hot atmosphere. This one won’t, so there is still time to monitor its progress.


SOHO is a project of international cooperation between ESA and NASA. SOHO’s science ranges from the Sun’s hot interior, through its visible surface and stormy atmosphere, and out to distant regions where the wind from the Sun battles with a breeze of atoms coming from among the stars.

Like most of the hundreds of comets found with the ESA-NASA sun-watching spacecraft, SOHO-422 was first noticed by an amateur astronomer. Pictures from SOHO are made available, freely and rapidly, on the Internet. People all around the world look especially at images from the LASCO C3 instrument, which covers the widest region of space, hoping for the honour of winning the race to spot the next incoming comet.

In this case XingMing Zhou of China was the sharp-eyed discoverer of what is officially designated as Comet 2002 G3 (SOHO). An animation of successive images of the comet shows it entering from the bottom left and following a curved track upwards. It passed behind a pillar that holds the mask blocking direct sunlight.


This morning, 17 April, the comet made its closest approach to the Sun. In the next few days it will continue upwards and to the right before moving out of the field of view.

Caution: This comet is visible only with SOHO’s special equipment. Do NOT try to see it by looking at the Sun for yourself -- the brightness will damage your eyes!

SOHO is a project of international cooperation between ESA and NASA. The spacecraft was built in Europe for ESA, equipped with instruments by teams of scientists in Europe and the USA, and launched by NASA December 1995.

Im Focus: A cavity leads to a strong interaction between light and matter

Researchers have succeeded in creating an efficient quantum-mechanical light-matter interface using a microscopic cavity. Within this cavity, a single photon is emitted and absorbed up to 10 times by an artificial atom. This opens up new prospects for quantum technology, report physicists at the University of Basel and Ruhr-University Bochum in the journal Nature.

Quantum physics describes photons as light particles. Achieving an interaction between a single photon and a single atom is a huge challenge due to the tiny...

Im Focus: Solving the mystery of quantum light in thin layers

A very special kind of light is emitted by tungsten diselenide layers. The reason for this has been unclear. Now an explanation has been found at TU Wien (Vienna)

It is an exotic phenomenon that nobody was able to explain for years: when energy is supplied to a thin layer of the material tungsten diselenide, it begins to...

Im Focus: An ultrafast glimpse of the photochemistry of the atmosphere

Researchers at Ludwig-Maximilians-Universitaet (LMU) in Munich have explored the initial consequences of the interaction of light with molecules on the surface of nanoscopic aerosols.

The nanocosmos is constantly in motion. All natural processes are ultimately determined by the interplay between radiation and matter. Light strikes particles...

Im Focus: Shaping nanoparticles for improved quantum information technology

Particles that are mere nanometers in size are at the forefront of scientific research today. They come in many different shapes: rods, spheres, cubes, vesicles, S-shaped worms and even donut-like rings. What makes them worthy of scientific study is that, being so tiny, they exhibit quantum mechanical properties not possible with larger objects.

Researchers at the Center for Nanoscale Materials (CNM), a U.S. Department of Energy (DOE) Office of Science User Facility located at DOE's Argonne National...

Im Focus: Novel Material for Shipbuilding

A new research project at the TH Mittelhessen focusses on the development of a novel light weight design concept for leisure boats and yachts. Professor Stephan Marzi from the THM Institute of Mechanics and Materials collaborates with Krake Catamarane, which is a shipyard located in Apolda, Thuringia.

The project is set up in an international cooperation with Professor Anders Biel from Karlstad University in Sweden and the Swedish company Lamera from...
