Is the universe really a "dark forest" full of hostile aliens in hiding?
We have no good reason to believe that aliens have ever contacted Earth. Sure, there are conspiracy theories and some rather strange reports about harm to cattle, but nothing credible. Physicist Enrico Fermi found this odd. His formulation of the puz.....»»
Researchers use the Dark Energy Spectroscopic Instrument to make the largest 3D map of our universe
With 5,000 tiny robots in a mountaintop telescope, researchers can look 11 billion years into the past. The light from far-flung objects in space is just now reaching the Dark Energy Spectroscopic Instrument (DESI), enabling us to map our cosmos as i.....»»
Meteorites: Why study them? What can they teach us about finding life beyond Earth?
Universe Today has explored the importance of studying impact craters, planetary surfaces, exoplanets, astrobiology, solar physics, comets, planetary atmospheres, planetary geophysics, and cosmochemistry, and how this myriad of intricately linked sci.....»»
Astronomers only knew of a single binary Cepheid system—they just found nine more
Measuring the distance to far away objects in space can be tricky. We don't even know the precise distance to even our closest neighbors in the universe—the Small and Large Magellanic Clouds. But, we're starting to get to the tools to measure it. O.....»»
Cosmochemistry: Why study it? What can it teach us about finding life beyond Earth?
Universe Today has had some fantastic discussions with researchers on the importance of studying impact craters, planetary surfaces, exoplanets, astrobiology, solar physics, comets, planetary atmospheres, and planetary geophysics, and how these diver.....»»
10 Stranger Things spinoffs we’d like to see after season 5
Since Netflix plans to expand the Stranger Things universe after season 5, they should consider these spinoff ideas that fans would love to see......»»
"Dark stars": Dark matter may form exploding stars, and observing the damage could help reveal what it"s made of
Dark matter is a ghostly substance that astronomers have failed to detect for decades, yet which we know has an enormous influence on normal matter in the universe, such as stars and galaxies. Through the massive gravitational pull it exerts on galax.....»»
NASA"s tiny BurstCube mission launches to study cosmic blasts
NASA's BurstCube, a shoebox-sized satellite designed to study the universe's most powerful explosions, is on its way to the International Space Station......»»
Astronomers find evidence that blue supergiant stars can be formed by the merger of two stars
An international piece of research, led by the Instituto de Astrofísica de Canarias (IAC) has found clues to the nature of some of the brightest and hottest stars in our universe, called blue supergiants. Although these stars are commonly observed,.....»»
Scientists find one of the most ancient stars that formed in another galaxy
The first generation of stars transformed the universe. Inside their cores, simple hydrogen and helium fused into a rainbow of elements. When these stars died, they exploded and sent these new elements across the universe. The iron running in your ve.....»»
Planetary geophysics: What is it? What can it teach us about finding life beyond Earth?
Universe Today has examined the importance of studying impact craters, planetary surfaces, exoplanets, astrobiology, solar physics, comets, and planetary atmospheres, and how these intriguing scientific disciplines can help scientists and the public.....»»
The mystery of consciousness shows there may be a limit to what science alone can achieve
The progress of science in the last 400 years is mind blowing. Who would have thought we'd be able to trace the history of our universe to its origins 14 billion years ago? Science has increased the length and the quality of our lives, and the techno.....»»
Largest-ever map of universe"s active supermassive black holes released
Astronomers have charted the largest-ever volume of the universe with a new map of active supermassive black holes living at the centers of galaxies. Called quasars, the gas-gobbling black holes are, ironically, some of the universe's brightest objec.....»»
The cosmic neutrino background would tell us plenty about the universe, says researcher
Readers of Universe Today are probably already familiar with the concept of the cosmic microwave background (CMB). Its serendipitous discovery by a pair of radio astronomers at Bell Labs is the stuff of astronomical legend. Over the past decades, it.....»»
