The first direct measurement of the bar-shaped collection of stars at the center of our Milky Way galaxy has been made by combining data from…
Astronomers have made a new measurement of how fast the universe is expanding, using an entirely different kind of star than previous endeavors. The revised…
Using Earth’s most powerful array of radio telescopes, astronomers have made the first observations of a circumplanetary disk of gas and dust like the one…
As if black holes weren’t mysterious enough, astronomers using NASA’s Hubble Space Telescope have found an unexpected thin disk of material furiously whirling around a…
Einstein’s theory of General Relativity is world-famous – but it might not be the only way to explain how gravity works and how galaxies form….
Astronomers have spotted a distant pair of titanic black holes headed for a collision. Each black hole’s mass is more than 800 million times that…
Astronomers obtained the first detailed face-on view of a gaseous disk feeding the growth of a massive baby star. They found that it shares many…
Researchers using the radio telescope ALMA (Atacama Large Millimeter/submillimeter Array) observed signals of oxygen, carbon, and dust from a galaxy in the early Universe 13…
Cyanide and carbon monoxide are both deadly poisons to humans, but compounds containing iron, cyanide, and carbon monoxide discovered in carbon-rich meteorites by a team…
The Kepler mission and its extension, called K2, discovered thousands of exoplanets. It detected them using the transit technique, measuring the dip in light intensity…
A group of astronomers led by Crystal Martin and Stephanie Ho of the University of California, Santa Barbara, has discovered a dizzying cosmic choreography among…
The Sun is why we’re here. It’s also why Martians or Venusians are not. When the Sun was just a baby four billion years ago,…
Astronomers have discovered a new class of “cold quasars” that could change our perception of how galaxies mature. The discovery was announced June 12 at…
The formation and growth of galaxies in the early universe is a key research topic for future giant telescopes like the Giant Magellan Telescope and…
Through decades of study, astronomers have developed a clearer picture of the chaotic and crowded neighborhood surrounding the supermassive black hole at the center of…
In this image, numerous sweeping arcs seem to congregate at various bright regions. You may wonder: What is being shown? Air traffic routes? Information moving…
Did ancient supernovae induce proto-humans to walk on two legs, eventually resulting in homo sapiens with hands free to build cathedrals, design rockets, and snap…
