A research team led by Ph.D. candidate Wang Haozhi under the supervision of Prof. Ali Esamdin at the Xinjiang Astronomical Observatory (XAO) of the Chinese Academy of Sciences (CAS) has revealed the genuine source of the pulsating star KOI-1755 transit signal using the Kepler space telescope. Their findings are published in The Astronomical Journal.

Large exoplanets are more easily detected than small ones. It’s axiomatic. While large planets block out more starlight during transits, small planets block out much less, letting them hide in the overpowering glare from their stars. To help detect sub-Jupiter mass exoplanets, astronomers search for the effect these planets can have on their surroundings.

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have made the highest resolution image to date, revealing new insights into the unusual and mysterious architecture of the debris disk encircling Fomalhaut, one of the brightest and most well-studied stars in our cosmic neighborhood.

Astronomers and students working together through a unique educational initiative have obtained a striking new image of the growing tail of interstellar Comet 3I/ATLAS. The observations reveal a prominent tail and glowing coma from this rare celestial visitor, while also providing new scientific measurements of its colors and composition.

This week marks 48 years since the Sept. 5, 1977, launch of NASA’s Voyager 1 spacecraft from Cape Canaveral, Florida, to study Jupiter and Saturn up close. Nearly a half-century later, Voyager 1 and its twin, Voyager 2 are still exploring. Only now they’re in the outer reaches of our solar system.

Ireland’s first satellite, EIRSAT-1, has completed its mission orbiting Earth. The CubeSat, which was built and launched by students and faculty of University College Dublin (UCD), will de-orbit in a day or two.

LIGO, the Laser Interferometer Gravitational-wave Observatory, has been called the most precise ruler in the world for its ability to measure motions more than 10,000 times smaller than the width of a proton. By making these extremely precise measurements, LIGO, which consists of two facilities—one in Washington and one in Louisiana—can detect undulations in space-time […]
JetBlue Airways will become the first airline to use Amazon’s Project Kuiper satellite network to power its in-flight Wi‑Fi service, the companies announced Wednesday, as the online retail giant tries to challenge the dominance of Elon Musk’s Starlink.

Scientists have discovered a giant black hole that they believe may have been formed in the first few microseconds after the Big Bang. The black hole is so huge that it may change our understanding of how these cosmic giants form. If the findings are confirmed, this will be the first evidence of primordial black […]
This dramatic scene captured by NASA’s James Webb Space Telescope looks like a fantastical tableau from J. R. R. Tolkien’s The Lord of the Rings. But truth is even stranger than fiction. In reality, what appears to be a craggy, starlit mountaintop kissed by wispy clouds is actually a cosmic dust-scape being sculpted by the […]
One of the most difficult parts of astronomy is understanding how time affects it. The farther away you look in the universe, the farther back you look in time. One way this complicates things is how objects might change over time. For example, a supermassive black hole at the center of a galaxy in the […]
A new systematic study of the atmospheric conditions at the Muztagh Station in western China has revealed the site’s unique suitability for optical observations. Researchers from the Xinjiang Astronomical Observatory of the Chinese Academy of Sciences reported that the location offers excellent “seeing” conditions, making it ideal for high-precision optical observations. The findings were published […]
As Earth moves through space, it wobbles slightly. A team of researchers from the Technical University of Munich (TUM) and the University of Bonn has now succeeded in measuring these fluctuations in Earth’s axis using a completely new method—until now, possible only through complex radio astronomy. The team used the high-precision ring laser at TUM’s […]
Researchers from the University of California San Diego Sanford Stem Cell Institute have discovered that spaceflight accelerates the aging of human hematopoietic stem and progenitor cells (HSPCs), which are vital for blood and immune system health.
