Aside from tracking asteroids that could endanger the planet, the telescope played a major role in the “SETI” program — the search for intelligent life. It was notably used by astronomer Carl Sagan to send an interstellar message.

Earlier this week, the facility was forced to close down after a cable supporting a metal platform above the telescope fell, tearing a 100-foot gash in its giant reflector dish.

“The cable didn’t really break in the sense of a cable kind of snapping, but it just sort of slipped from its socket, which is you know, an even weirder condition,” Arecibo Observatory Director Francisco Cordova told CBS News’ Jeff Glor.

Oftentimes, when we think about aliens, we think about little green men with powerful lasers. However, what if I were to tell you that alien microbes — or space viruses- were the deadliest kind of alien?

Very odd posssibly some life form or possibly energy wave.

Space Mysteries: When scientists put their ear to the early universe, they found it yelled back.

Scientists are ramping up their efforts in the search for signs of alien life.

Experts at the SETI Institute, an organization dedicated to tracking extraterrestrial intelligence, are developing state-of-the-art techniques to detect signatures from space that indicate the possibility of extraterrestrial existence.

These so-called “technosignatures” can range from the chemical composition of a planet’s atmosphere, to laser emissions, to structures orbiting other stars, among others, they said.

Invisible radio signals from the cosmos have revealed previously unknown phenomena from prebiotic molecules in a starburst about 250 million light-years from Earth to the true rotation of Mercury. But the most famous occurred on August 6, 1967, when a squiggly stretch of high-speed recordings occupying less than a quarter-inch of astronomer Jocelyn Bell Burnell’s radio-telescope readouts revealed the first sign of something strange — an unknown cosmic mystery.

The minuscule signal appeared over and over again in the same part of the sky and she realized she was looking at a cosmic mystery — a repeating string of radio pulses spaced a bit more than a second apart that were unlike anything anyone had ever seen before. Bell-Burnell had detected the first evidence of a pulsar LGM-1 for Little Green Men. They thought the pulses could possibly be a beacon from an alien source.

Fast forward to today — mysterious circles of radio waves have left astronomers who are part of a pilot survey for a new project called the Evolutionary Map of the Universe (EMU) baffled with no idea how they formed, or even how big or far away they are. They don’t seem to match anything that has been seen before in the cosmos. The researchers dubbed them Odd Radio Circles, or ORCs.

Astronomers have discovered an activity cycle in another fast radio burst, potentially unearthing a significant clue about these mysterious deep-space phenomena.

Fast radio bursts, or FRBs, are extragalactic flashes of light that pack a serious wallop, unleashing in a few milliseconds as much energy as Earth’s sun does in a century. Scientists first spotted an FRB in 2007, and the cause of these eruptions remains elusive nearly a decade and a half later; potential explanations range from merging superdense neutron stars to advanced alien civilizations.

NASA is currently planning to return astronauts Bob Behnken and Doug Hurley to Earth on board SpaceX’s Crew Dragon spacecraft in about two weeks, the space agency told CNBC on Friday.

The spacecraft, which the astronauts named Endeavour, is scheduled to splash down in the Atlantic Ocean on Aug. 2 at about 3 p.m. ET, according to NASA’s Johnson Space Center public affairs officer Kyle Herring.

Herring noted that the departure time from the International Space Station “is a bit of a moving target,” but said in an email that the spacecraft is scheduled to un-dock at about 8 p.m. ET on Aug. 1. NASA will look more closely at the weather forecasts for where the spacecraft might splash down after the astronauts perform a spacewalk next week. NASA Administrator Jim Bridenstine also confirmed those dates.

Venus has always been a bit of the odd stepchild in the solar system. It’s similarities to Earth are uncanny: roughly the same size, mass, and distance from the sun. But the development paths the two planets ended up taking were very different, with one being the birthplace of all life as we know it, and the other becoming a cloud-covered, highly pressurized version of hell. That cloud cover, which is partially made up of sulfuric acid, has also given the planet an air of mystery. So much so that astronomers in the early 20th century speculated that there could be dinosaurs roaming about on the surface.

Some of that mystery will melt away if a team from NASA’s Jet Propulsion Laboratory gets a chance to launch their newest idea for a mission to the planet, the Venus Emissivity, Radio Science, InSAR, Topograph, and Spectroscopy (or VERITAS) mission.

Earth, as we know it, is only teeming with life because of the influence of our Sun. Its light and heat provides every square meter of Earth — when it’s in direct sunlight — with a constant ~1500 W of power, enough to keep our planet at a comfortable temperature for liquid water to continuously exist on its surface. Just like the hundreds of billions of stars in our galaxy amidst the trillions of galaxies in the Universe, our Sun shines continuously, varying only slightly over time.

But without quantum physics, the Sun wouldn’t shine at all. Even in the extreme conditions found in the core of a massive star like our Sun, the nuclear reactions that power it could not occur without the bizarre properties that our quantum Universe demands. Thankfully, our Universe is quantum in nature, enabling the Sun and all the other stars to shine as they do. Here’s the science of how it works.
