Astronomers have discovered a giant stream of gas flowing from neighboring galaxies around the Milky Way is more than 40% longer and 2.5 billion years older than previously known, according to new radio observations.
The ALMA team successfully linked three antennas, correcting errors that can arise when using only two antennas, paving the way for precise, high-resolution imaging. The successful test shows that the completed ALMA system of 66 high-tech antennas will produce astronomical images of unprecedented quality.
Astronomers are using a record-breaking 35-telescope array to measure the sky with extreme precision. The project aims to create a stronger, more precise reference grid for celestial positions.
Astronomers use VLA to study GRB 090423, a stellar explosion 13 billion light-years away, and discover it was more energetic than typical GRBs. The team also finds that the blast expanded into a uniform gaseous medium surrounding the star, providing unique insights into the early universe.
The ALMA telescope has successfully transported its first antenna to a high-altitude site in Chile, marking the start of the next phase of the project. The move allows for improved astronomical observations using millimeter and submillimeter wavelengths, key to exploring cosmic origins.
Researchers used VLBA system to measure bending of starlight by gravity, achieving precision of one part in 30,000. The accurate measurement brings scientists closer to uniting General Relativity and quantum theory.
Using a worldwide VLBA collaboration, scientists pinpoint the origin of superenergetic gamma rays coming from M87's core near the supermassive black hole. The discovery sheds light on the mechanisms powering galaxies' energetic jets.
A team of astronomers has directly measured the distance to a galaxy, providing a precise tool for unraveling the mystery of Dark Energy. The technique uses water molecules in disks orbiting central black holes to amplify radio waves, enabling measurements up to 160 million light-years away.
Astronomers have discovered a unique double-star system that represents a 'missing link' stage in the birth process of millisecond pulsars. The system, J1023, shows evidence for an accretion disk surrounding the neutron star before it disappeared and the pulsar emerged.
Researchers have discovered complex organic molecules in interstellar space using powerful radio telescopes. Detailed images of protoclusters reveal a complex mix of stars in different stages of formation.
The ALMA Observatory has accepted its first North American antenna, marking a significant milestone in the project. The 12-meter-diameter antenna was delivered by General Dynamics SATCOM Technologies and will enable astronomers to probe phenomena beyond the reach of visible-light telescopes with unprecedented sharpness.
A recent study suggests that supermassive black holes formed first and grew before their host galaxies. The ratio of black hole mass to galactic bulge mass is nearly constant across different galaxy sizes and ages. This finding implies that the growth of black holes and galaxies was an interactive process.
The Milky Way galaxy is rotating about 100,000 miles per hour faster than previously understood, increasing its mass by 50 percent. This increase in speed and mass brings the Milky Way closer to colliding with the Andromeda Galaxy or smaller nearby galaxies.
A team of scientists used a natural cosmic lens to capture an image of a distant galaxy in the early Universe. The image shows a massive reservoir of gas and a supermassive black hole feeding a burst of star formation, indicating that the galaxy has collided with another.
Scientists will explore chemical reactions in extreme space conditions using a new research center combining laboratory experiments, theoretical studies, and radio-telescope observations. The Center for Chemistry of the Universe aims to expand our understanding of molecule formation that may seed young planets with life.
Astronomers detected a strong magnetic field in a 6.5 billion-year-old protogalaxy, contradicting the leading theory that magnetic fields should weaken with time. The discovery was made using the National Science Foundation's ultra-sensitive Robert C. Byrd Green Bank Telescope.
Researchers used a rare double-star system to test Albert Einstein's theory of General Relativity, finding that the famed physicist's 93-year-old theory has passed yet another test. The study confirmed that the strong gravity of the neutron stars causes one to wobble or precess.
Researchers have used radio telescopes to study the behavior of Seyfert galaxies, revealing that the majority of them are being consumed by black holes due to interactions with neighboring galaxies. This discovery provides strong evidence for the role of galactic cannibalism in powering these galaxies.
Astronomers used VLBA to watch material winding a corkscrew path and confirm twisted magnetic fields accelerate particles. The team observed BL Lac, a blazar, with unprecedented view of the innermost portion of its jet.
The Atacama Large Millimeter/submillimeter Array (ALMA) will provide astronomers with unprecedented views of the origins of stars, galaxies, and planets. ALMA's high-resolution capabilities will enable scientists to unravel longstanding mysteries in astronomy.
Researchers discovered two new aldehyde molecules, propanal and propenal, in an interstellar cloud near the Milky Way Galaxy. These findings provide insights into the formation chemistry of complex molecules in space.
The Green Bank Telescope (GBT) is the world's largest fully steerable radio telescope, opening a new era of astronomical research. With its record-breaking capabilities, scientists will be able to study the universe in unprecedented detail, making groundbreaking discoveries and advancing our understanding of the cosmos.
