This is where it all started. Michael Tzukran in the old observatory on the roof of the Shenkar building

The satellite observatory is located at Tel Aviv University

The new observatory of planets and satellites that is currently being built on the roof of the Shenkar building will become one of the most sophisticated laboratories in the world, which will allow, among other things, advanced communication with satellites and other spacecraft

Directing a view to the edge of the universe: the Weizmann Institute joins the partnership with the giant "Magellan" telescope in Chile

The joining will open up new possibilities for the institute's scientists in space research and will allow them to observe billions of light-years away with a resolution 10 times higher than that of the Hubble Space Telescope.

The researchers developed an amplifier - a medium containing atoms that the photon coming from space passes through after the telescope key. The impact of the photon on the atom forces the atom to release a large number of photons identical to the original photon. The improvement in resolution will benefit any telescope, especially for medium-sized telescopes, and in particular for space telescopes

The scientists observed the black hole in the center of the galaxy M87 that was photographed about three years ago by optical means, and now the huge magnetic field around it has been photographed which reveals what happens when matter approaches the speed of light and part of it is swallowed up by the black hole. The writer is one of the scientists who participated in the project

When building the next giant telescope in the Atacama Desert in Chile, changes in winds and visibility as a result of global warming must be taken into account, even in the most remote areas, especially when planning a facility that will operate for about a century
In the figure, Australia's main science agency CISRO's ASKAP radio telescope detected a fast radio burst and determined its exact location. Ground-based telescopes around the world, KECK, VLT and Gemini, were then directed to follow-up observations of the galaxy where the event occurred. CSIRO / Andrew Howells

In the picture the star system closest to the Sun - the double star Alpha Stanauri A and B and their distant companion - Proxima Centauri. At the end of 2016, the European Southern Observatory (ESO) signed an agreement with the Breakthrough initiative to adapt the Very Large Telescope (VLT) instruments to search for planets in the Alpha Centauri system. These planets could be targets for the Breakthrough Starshot initiative to launch tiny spacecraft into this system. Photo: ESO/B.

From left to right: astronomical photons are emitted from the star, pass through the lens and reach an amplifier containing atoms. An atom hit by an astronomical photon in response emits a large amount of forced photons (in green), which hit the telescope detector and "report" with high precision the direction of impact of the original (astronomical) photon. Most of the spontaneous photons (in red) scatter to the sides and are not absorbed by the detector; Therefore, the noise is low and the separation is not significantly impaired.

A method developed in collaboration with researchers at the Technion is expected to bring about a dramatic improvement in the separation ability of telescopes
