Astronomers Detect Millions of Signals From an Intelligent Civilization: Us
We know - we're proof of it - that intelligent civilisations (yes, civilisations ) are possible. Finding signs of other civilisations in the Milky Way galaxy is not such a simple matter, but we do have tools at our disposal. Based on our own technological capabilities, we can extrapolate what signals alien technology might emit, and search for those.
These signs are called technosignatures, and our efforts in the search for extraterrestrial intelligence (SETI) revolve around them, particularly in radio wavelengths.
Huge Puerto Rico radio telescope to close in blow to science - ABC News
The independent, federally funded agency said it's too dangerous to keep operating the single dish radio telescope -- one of the world's largest -- given the significant damage it recently sustained. An auxiliary cable broke in August and tore a 100-foot hole in the reflector dish and damaged the dome above it. Then on Nov. 6, one of the telescope's main steel cables snapped, leading officials to warn that the entire structure could collapse.
NSF officials noted that even if crews were to repair all the damage, engineers found that the structure would still be unstable in the long term.
Phosphine might not exist on Venus after all
This colorized picture of Venus was taken February 14, 1990, by the Galileo spacecraft from a distance of almost 1.7 million miles. It has been colorized to a bluish hue to emphasize subtle contrasts in the cloud markings.

The detection of phosphine gas in Venus's atmosphere, announced last month , ignited a firestorm of speculation about whether the gas could be produced by alien microbes on the planet, where NASA is currently considering sending a spacecraft . However, three independent studies now have failed to find evidence of phosphine in the Venusian atmosphere.

Sun-Like Star Identified As the Potential Source of the Wow! Signal | Discover Magazine
The Big Ear Radio Telescope in Delaware, Ohio, was disassembled in 1998 having operated for over 30 years. It was replaced by a golf course. Big Ear was never the world's biggest radio telescope, nor its most sensitive. But Big Ear nevertheless made one of the most famous observations in the history of astronomy, one that till this day has never been explained.
Throughout the 1970s, Big Ear searched for signals from extraterrestrial civilizations. And on Aug. 15, 1977, it found one — a strong, intermittent signal lasting for 72 seconds, that stood out from the background noise like a searchlight.
Scientists expand space instrument's capabilities: Researchers add second dating technique to
A new study by Southwest Research Institute scientists describes how they have expanded the capabilities of the prototype spaceflight instrument Chemistry Organic and Dating Experiment (CODEX), designed for field-based dating of extraterrestrial materials. CODEX now uses two different dating approaches based on rubidium-strontium and lead-lead geochronology methods. The instrument uses laser ablation resonance ionization mass spectrometry (LARIMS) to obtain dates using these methods.
Carl Edward Sagan: Iconic US astronomer who demystified space - ht school - Hindustan Times
Born on November 9, 1934, in Brooklyn, New York, to Rachel Molly Gruber, a housewife, and Samuel Sagan, an immigrant worker from the then Russian empire, Carl Sagan received his first lessons at a local elementary school. As a boy, he developed interest in astronomy when he learnt that the Sun was a star. He enrolled at the University of Chicago where he earned his PhD in astronomy and astrophysics.

In 1960, Sagan was appointed the Miller Fellow at the University of California, Berkeley. There, he helped a team of astrophysicists develop an infrared radiometer for NASA’s Mariner 2 robotic probe.
