Red Dwarf Star

Artist's depiction of the powerful flare that erupted from the red dwarf star EV Lacertae in 2008.

Unlike Earth, Venus lacks a magnetic field to deflect powerful solar outbursts -- as can be seen in this NASA-created image, a still from the video "Dynamic Earth: Exploring Earth's Climate Engine."

This vertigo-inducing, false-color image from NASA's Cassini mission highlights the storms at Saturn's north pole. The angry eye of a hurricane-like storm appears dark red while the fast-moving hexagonal jet stream framing it is a yellowish green. Low-lying clouds circling inside the hexagonal feature appear as muted orange color. A second, smaller vortex pops out in teal at the lower right of the image. The rings of Saturn appear in vivid blue at the top right.

This Hubble photo is of a small portion of a large star-birthing region in the Carina Nebula. Towers of cool hydrogen laced with dust rise from the wall of the nebula.

This computer simulation shows gas from a tidally shredded star falling into a black hole. Some of the gas also is being ejected at high speed into space.

This image of Asia and Australia at night is a composite assembled from data acquired by the Suomi NPP satellite in April and October 2012.

In this composite image, visible-light observations by NASAs Hubble Space Telescope are combined with infrared data from the ground-based Large Binocular Telescope in Arizona to assemble a dramatic view of the well-known Ring Nebula.

A delicate ribbon of gas floats eerily in our galaxy. A contrail from an alien spaceship? A jet from a black-hole? Actually this image, taken by NASA's Hubble Space Telescope, is a thin section of a supernova remnant caused by a stellar explosion that occurred more than 1,000 years ago.

NASA's Hubble Space Telescope caught Jupiter's moon Ganymede playing a game of "peek-a-boo." In this crisp image, Ganymede is shown just before it ducks behind the giant planet.

While amateur radio enthusiasts have been able to communicate with astronauts on the International Space Station since its inauguration in 2000, a new digital amateur television (DATV) transmitter installed in the Columbus laboratory will add a visual element to those conversations, the European Space Agency announced on Monday.

For the past 14 years, people on Earth have been able to communicate with the ISS crew using standard radio equipment, the ESA said. The DATV system was developed by Kayser Italia and arrived at the station last August on board Japans space freighter. It was then connected to an existing S-band antenna in the Columbus laboratory.

The video signal works like standard TV broadcasts in that the crew members will not be able to see their audience, but they will be able to hear their questions and comments over the regular amateur radio system. The sessions have to be brief, as the connection requires a direct line of sight. Since the ISS travels at speeds of more than 17,000 mph, it quickly passes through the field of view of Earth-based amateur stations, the agency said.

The crew finished commissioning the set-up for the device on April 12, and NASA astronaut Mike Hopkins was the first member to broadcast over what has been dubbed Ham TV. He took part in a video chat with ground stations in Livorno, Casale Monferrato and Matera, Italy.

The ESA explained that they have contributed five ground antennas and equipment to the Amateur Radio on the International Space Station (ARISS) organization, which can be easily transported and repositioned as needed in order to receive video from the ISS when it flies overhead. When linked together, the agency said that the station is capable of providing up to 20 minutes of contact at any given time.

According to ARISS, the Ham Video transmitted operates with a Canon XF-305 camera. It has download frequencies of 2.422 GHz and 2.437 GHz, contingency frequencies of 2.369 GHz and 2.395 GHz, and a DVB-S like signal. Other characteristics include a DVB-S like signal (without PMT tables), symbol rates of 1.3 Ms/s, 2.0 Ms/s, FEC of 1/2, video PID of 256, audio PID 257 and RF radiated power (approximately 10 W EIRP).

Astronauts on the International Space Station can now talk with people on Earth with video using simple transmitters. 'Ham TV' has been set up in ESA's Columbus laboratory and already used for talking with ground control.

Amateur radio enthusiasts have been able to poll astronauts circling our planet using standard radio equipment since the Station was inaugurated in 2000. Radio signals easily reach the orbital outpost flying 350 km above us on sets readily available to radio enthusiasts.

The new Ham TV adds a visual dimension, allowing an audience on the ground to see and hear the astronauts.

The hardware, developed by Kayser Italia, was sent to the Station on Japan's space freighter in August last year and connected to an existing S-band antenna on Columbus.

NASA astronaut Mike Hopkins had the honour of being the first to commission the unit and broadcast over Ham TV. He had a video chat with three ground stations in Italy: Livorno, Casale Monferrato and Matera. The crew finished commissioning the set-up on 12 April for general use.

Just like standard television, the video signal is one way. The astronauts cannot see their audience but they will still be able to hear them over the traditional amateur radio on the Station.

Contacts are brief the connection requires direct line of sight and the Station's 28 800 km/h means it quickly passes through the field of view of amateur stations.

ESA has provided five ground antennas and equipment to the Amateur Radio on the International Space Station organisation to receive video from the Station. These stations can be transported easily and positioned to follow the laboratory as it flies overhead. Linked together in this way, the stations can supply up to 20 minutes of contact at a time.
