Black holes are some of the strangest objects in the universe, and they typically fall into one of two size extremes: “small” ones that are dozens of times more massive than the sun and other “supermassive” black holes that are billions of times larger than our nearest star. But until now, astronomers had not seen good evidence of anything in between.
Russian scientists say they made a “unique” discovery while analyzing samples from the exterior of the International Space Station – traces of tiny sea creatures on the station’s windows and walls. It remains unclear how marine plankton ended up in space.
Through the analysis of light from distant galactic clusters, astronomers have detected a mysterious signal that they’re having a hard time explaining. Although the signal is weak, could it be the much sought-after direct evidence for dark matter? Dark matter pervades the entire universe and makes up for the bulk of its mass, but what is it? We know it’s out there and oodles of indirect evidence for its presence, but seeing a direct signal has so far proven elusive.
Our universe may have emerged from a black hole in a higher-dimensional universe, propose a trio of Perimeter Institute researchers. What we perceive as the big bang, they argue, could be the three-dimensional “mirage” of a collapsing star in a universe profoundly different than our own.
The “Rosetta” spacecraft has arrived at and orbited comet 67P – located more than 250 million miles away – bringing a 10-year journey across the solar system to an end.
Witness the recent trend of modern-day science catching up to an ancient understanding about the true nature of reality, its make-up, how it functions and how we can work with it to bring about change on our planet.
Astronomers using NASA’s Chandra X-ray Observatory to explore the Perseus Cluster, a swarm of galaxies approximately 250 million light years from Earth, have observed the spectral line that appears not to come from any known type of matter. The signal they received cannot be explained by known physics but they say it shifts suspicion to the dark matter.
Astronomers have a mystery on their hands. Two large radio telescopes, on opposite sides of the planet, have detected very brief, very powerful bursts of radio waves. Right now, astronomers have no idea what’s causing these bursts or where they’re coming from. And nothing has been ruled out at the moment — not even the kind of outrageous claims you’d expect to see in tabloid headlines.
An international team of astronomers discovered another “Earth-like” planet that may be capable of sustaining life. Five times the size of Earth, “Gliese 832 c” is 16 light years away and appears to have a habitable zone and water, opening the possibility for life existing on the planet. Gliese 832c goes around its host star every 36 days. But that host star is a red dwarf that’s much dimmer and cooler than our sun, so Gliese 832c receives about as much stellar energy as Earth does, despite orbiting much closer to its parent..
A mystery object that appeared and then vanished again from a giant lake on Titan, the largest moon of Saturn. The sighting could be an iceberg that broke free of the shoreline, an effect of rising bubbles, or waves rolling across the normally placid lake’s surface, scientists say.
Pluto has long been regarded as something of an anomaly in our solar system. Compared to neighboring worlds, the dwarf planet has an extremely tilted orbit which sometimes brings it closer to the sun than Neptune. Now, astronomers in Spain believe it has yet another unusual feature – the world may be harboring two supersized planets just out of reach of our telescopes.
