Vintage NASA: See Voyager’s 1990 ‘Solar System Family Portrait’ debut

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 completes its mission

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.

New algorithm hushes unwanted noise in LIGO, may lead to more black hole discoveries

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 […]

Amazon’s Starlink rival lands first major airline deal

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.

The cosmic giant challenging our understanding of galaxy formation in the early universe

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 […]

Zooming in on Pismis 24, Webb gets glittering glimpse of star birth

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 […]

BlueDOGs might evolve from Little Red Dots

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 […]

Study confirms excellent astronomical potential of Muztagh Observation Station

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 […]

No radio astronomy needed: Ring laser measures Earth’s axis wobble with unprecedented precision

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 […]

Spaceflight accelerates human stem cell aging, researchers find

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.

Astronomers discover one of the most massive binary stars in the galaxy

A research team has used both archival Hubble Space Telescope data and new observations to precisely measure the binary star system NGC3603-A1. One star weighs about 93 times the mass of our sun, while its companion tips the scales at roughly 70 solar masses. Together, they represent one of the most massive binary systems ever […]

Webb captures dusty wisps round a planet-forming disk

For this new Picture of the Month feature, the NASA/ESA/CSA James Webb Space Telescope has provided a fantastic new view of IRAS 04302+2247, a planet-forming disk located about 525 light-years away in a dark cloud within the Taurus star-forming region. With Webb, researchers can study the properties and growth of dust grains within protoplanetary disks […]

Is there life on Saturn’s moon? Where there’s water, there’s a chance

At first glance, Saturn’s moon Enceladus seems rather unremarkable: it is much smaller than the Earth’s moon and is far away and completely covered in ice.
