World-Renowned Arecibo Radio Telescope can't be saved

The world-renowned radio telescope at the Arecibo Observatory in northern Puerto Rico, now on the brink of collapse, is set to be withdrawn from service, the National Science Foundation (NSF) announced today.

Astronomy: Unfolding formation of a massive star in action

Socorro - Images of a young star system taken 18 years apart have revealed astonishing changes, giving astronomers a unique perspective on stars at the earliest stage of their formation.

Radar 'unclothes' planet Venus

Green Bank - As a planet, Venus, shrouded in thick clouds of carbon dioxide, doesn’t lend itself to visual observation. To lift the veil on Earth’s nearest planetary neighbor, spacecraft such as NASA’s Magellan probe use radar to penetrate Venus' clouds.

Medium-size black hole in galaxy NGCC 2276 fills evolutionary gap

Black holes come in three sizes, small, medium and large. Small and large black holes have representative candidates to support black hole theory. A medium-sized candidate has been identified in a spiral galaxy 100 million light-years from Earth.

New radar images reveal what lies beneath Moon's surface

Charlottesville - A joint effort using the resources of two of the world’s largest radio telescopes has revealed previously unseen features deep below the surface of the Moon.

Conceptual design milestone for SKA

Manchester - The Square Kilometre Array (SKA) radio telescope has successfully passed the System Engineering Conceptual Design Review, an important milestone for this huge international project.

Workshop will gather analysis ideas for SKA

Aveiro - A workshop planned for 24-25 May in Portugal to examine latest information and trends in radio astronomy data analysis, will contribute towards decisions affecting the huge planned Square Kilometer Array (SKA) radio telescope.

A projection of the radar data of Venus collected in 2012. Striking surface features -- like mountains and ridges -- are easily seen. The black diagonal band at the center represents areas too close to the Doppler “equator” to obtain well-resolved image data.

Artist's conception of the development of W75N(B)-VLA-2.. At left, a hot wind from the young star expands nearly spherically, as seen in 1996. At right, as seen in 2014, the hot wind has been shaped by encountering a dusty, donut-shaped torus around the star and appears elongated.
