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: First quantum photonic circuit with electrically driven light source

Optical quantum computers can revolutionize computer technology. A team of researchers led by scientists from Münster University and KIT now succeeded in putting a quantum optical experimental set-up onto a chip. In doing so, they have met one of the requirements for making it possible to use photonic circuits for optical quantum computers.

Optical quantum computers are what people are pinning their hopes on for tomorrow’s computer technology – whether for tap-proof data encryption, ultrafast...

Im Focus: OLED microdisplays in data glasses for improved human-machine interaction

The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP has been developing various applications for OLED microdisplays based on organic semiconductors. By integrating the capabilities of an image sensor directly into the microdisplay, eye movements can be recorded by the smart glasses and utilized for guidance and control functions, as one example. The new design will be debuted at Augmented World Expo Europe (AWE) in Berlin at Booth B25, October 18th – 19th.

Im Focus: Artificial Intelligence Helps in the Discovery of New Materials

With the help of artificial intelligence, chemists from the University of Basel in Switzerland have computed the characteristics of about two million crystals made up of four chemical elements. The researchers were able to identify 90 previously unknown thermodynamically stable crystals that can be regarded as new materials. They report on their findings in the scientific journal Physical Review Letters.

Im Focus: Complex hardmetal tools out of the 3D printer

For the first time, Fraunhofer IKTS shows additively manufactured hardmetal tools at WorldPM 2016 in Hamburg. Mechanical, chemical as well as a high heat resistance and extreme hardness are required from tools that are used in mechanical and automotive engineering or in plastics and building materials industry. Researchers at the Fraunhofer Institute for Ceramic Technologies and Systems IKTS in Dresden managed the production of complex hardmetal tools via 3D printing in a quality that are in no way inferior to conventionally produced high-performance tools.

Fraunhofer IKTS counts decades of proven expertise in the development of hardmetals. To date, reliable cutting, drilling, pressing and stamping tools made of...

Im Focus: Launch of New Industry Working Group for Process Control in Laser Material Processing

At AKL’16, the International Laser Technology Congress held in May this year, interest in the topic of process control was greater than expected. Appropriately, the event was also used to launch the Industry Working Group for Process Control in Laser Material Processing. The group provides a forum for representatives from industry and research to initiate pre-competitive projects and discuss issues such as standards, potential cost savings and feasibility.

In the age of industry 4.0, laser technology is firmly established within manufacturing. A wide variety of laser techniques – from USP ablation and additive...
