Astronomers Measure the Long Reach of a Quasar

There are a number of things in the Universe that could wipe out life as we know it, but — for now, and for Earth — a blast from our galaxy's supermassive black hole isn't one of them. That's not to say that Sagittarius A* doesn't pose a danger. If it wakes up someday and blasts out a strong wind, that definitely could affect Earth. It could well have powered a quasar in the past, and could do so again. from Universe Today https://ift.tt/GH2D4VE via IFTTT

Mercury's Weak Magnetic Field Periodically Traps Solar Wind

The planet Mercury is the first planet from the Sun but also one shrouded in mystery. This is primarily due to the limited number of spacecrafts that have visited it, but this limited data has provided scientists with new and exciting characteristics previously thought impossible. One fascinating aspect is its magnetic field, which was first discovered in March 1974, which both surprised and puzzled scientists due to the planet’s small size, which is measured at about half the size of the continental United States from coast to coast. from Universe Today https://ift.tt/GPf5i2r via IFTTT

Radio Array Detects Polarized Light From a GRB

On March 10, 2026, the Fermi telescope gamma-ray burst team reported the detection of a long-duration gamma ray burst that occurred when a star exploded inside a dense, highly magnetized cloud of hydrogen gas. That HII region is a bubble of ionized hydrogen created by winds from a massive young star. Astronomers immediately turned as many telescopes as possible to view the burst and its afterglow, including the NSF's Karl Jansky Very Large Array. from Universe Today https://ift.tt/aXtldfV via IFTTT

Tracking Satellites and Space Debris Using Radio Antennae

Every year, thousands and thousands of satellites get launched into orbit around our planet. The result is an increasingly congested "space" above Earth populated by equipment that provides services to the surface. At the same time, these satellites affect ground-based astronomy research and create potential for damage when they eventually fall through Earth's atmosphere to the ground. In addition, near-Earth space hosts old rocket bodies and other materials left in space by past missions. from Universe Today https://ift.tt/1qf5gET via IFTTT

The Risks of Debris Between the Earth and the Moon for Future Exploration

Radio Astronomy is Getting a Big Boost from the VLA's New Sky Survey

The National Radio Astronomy Observatory has completed a new survey with the updated Karl G. Jansky Very Large Array (VLA) in New Mexico. It's called the VLASS, the Very Large Array Sky Survey, and it's the most detailed radio survey of the sky ever completed. The VLA used the power of its 28 movable dishes to complete the survey. from Universe Today https://ift.tt/Sj8MdUF via IFTTT

White Dwarfs Eat More Planetary Debris Than Thought, But Magnetic Fields Hide It

Planetary debris disks around white dwarfs appear to be more plentiful than thought. That's because some white dwarfs are magnetic, and those magnetic fields create patches of metallic debris near the stars' poles, where it's more difficult to detect. This leads to an underestimation of debris, something new research is trying to correct. from Universe Today https://ift.tt/4o2lSNU via IFTTT
