Astronomers discover an Earth-sized “pi-planet” with an orbit of 3.14 days

Scientists at MIT and elsewhere have discovered an Earth-sized planet that revolves around its star every 3.14 days. Photo credit: NASA Ames / JPL-Caltech / T. Pyle, Christine Daniloff, MIT In a wonderful correspondence of astronomy and math, scientists at MIT and elsewhere have discovered a “pi-earth” – an Earth-sized planet that revolves around its star every 3.14 days and …

Our view of space will become more blurry as our planet warms, astronomers warn

The world’s most advanced telescopes were not made for today’s temperatures and interfere with our observations of the night sky. Three decades of data from the Paranal Observatory in northern Chile – home of the European Southern Observatory’s Very Large Telescope (VLT) – have shown several ways in which climate change is already affecting astronomical observations. And different ways it …

SpaceX satellites clutter the skies, frustrating astronomers

Appearance! Up in the sky! It’s a bird! It’s an airplane! Hundreds of satellites are messing up the galaxy. A multitude of massive internet satellites, launched by eco-friendly billionaire Elon Musk, are swirling over us – and astronomers are trying hard to figure out how to deal with the glaring reflection of the sun on these artificial orbiters. “There is …

Astronomers capture stellar winds in unprecedented detail

The stellar wind from R Aquilae resembles the structure of rose petals. Photo credit: L. Decin, ESO / ALMA Astronomers have provided an explanation for the shapes of planetary nebulae. The discovery is based on a series of observations of stellar winds around aging stars. Contrary to general consensus, the team found that stellar winds are not spherical, but rather …

Astronomers discover the first known planet orbiting a white dwarf star

Artist’s impression of a Jupiter-sized planet in orbit around a white dwarf. Incredibly, the two objects in the picture are actually to scale, as white dwarfs are roughly the size of Earth. image:: NASA / JPL The unprecedented discovery of a Jupiter-sized planet in orbit around a white dwarf star suggests that planets can survive the turbulent death struggles of …

Three HUGE asteroids headed toward Earth after amateur astronomers discovered massive space rocks that were missing our planetary defenses. MISSED – RT World News

Scientists can better spot incoming, “potentially dangerous” asteroids. Three more with a diameter of more than 15 meters are on the way this week. However, asteroid hunters only missed a 1,000-meter-high space rock last month. Earth is almost constantly threatened by space debris in the form of asteroids and meteorites, and this week is no exception as two smaller space …

Astronomers find a possible sign of life on Venus

Traces of a rare molecule known as phosphine have been found in the hellish, highly acidic atmosphere of Venus, astronomers said Monday – a tantalizing clue to the possibility of life. Phosphine molecules found on Earth are primarily a result of human industry or the action of microbes that thrive in oxygen-free environments. The researchers do not claim that life …
