Old Data, New Tricks Discover Pulsar in Galactic Plane
July 3, 2024 at 10:00 am | News Release

A team of astronomers has found a new tool to discover pulsars. Pulsars are rapidly rotating neutron stars that blast out pulses of radiation at regular intervals ranging from seconds to milliseconds.

Astronomers Discover Jupiter-sized Objects Drawn into Each Other’s Orbit
February 12, 2024 at 3:11 pm | News Release

What happens to planet-sized objects that don’t have a star? A team of astronomers studying Jupiter-mass binary objects (JuMBOs) in the Orion Nebula are gaining a new understanding of these unusual systems.

This artist’s illustration depicts the findings of a new study about the supermassive black hole at the center of our Galaxy called Sagittarius A (abbreviated as Sgr A). This result found that Sgr A* is spinning so quickly that it is warping spacetime – that is, time and the three dimensions of space – so that it can look more like a football.

The new study suggests that Sgr A is, in fact, spinning very rapidly, which causes the spacetime around it to be squashed down. The illustration shows a cross-section of Sgr A and material swirling around it in a disk. The black sphere in the center represents the so-called event horizon of the black hole, the point of no return from which nothing, not even light, can escape.

Looking at the spinning black hole from the side, as depicted in this illustration, the surrounding spacetime is shaped like a football. The faster the spin the flatter the football.

The yellow-orange material to either side represents gas swirling around Sgr A*. This material inevitably plunges towards the black hole and crosses the event horizon once it falls inside the football shape. The area inside the football shape but outside the event horizon is therefore depicted as a cavity. The blue blobs show jets firing away from the poles of the spinning black hole. Looking down on the black hole from the top, along the barrel of the jet, spacetime is a circular shape.
Telescopes Show the Milky Way’s Black Hole is Ready for a Kick

COSMIC: SETI Institute Unlocks Mysteries of the Universe with Breakthrough Technology at the Very Large Array
January 8, 2024 at 12:02 pm | Announcement

In a groundbreaking cosmic quest, the SETI Institute’s Commensal Open-Source Multimode Interferometer Cluster (COSMIC) at the Karl G. Jansky Very Large Array (VLA) is expanding the search for extraterrestrial intelligence (SETI). This cutting-edge technology is not a distinct telescope; it’s a detector. COSMIC searches for extraterrestrial signals and paves the way for future science using a copy of the raw data from the telescope’s observations.

Zach Gallegos is a shining example of dedication and hard work. His journey from a security guard to the HVAC and Plumbing lead at the VLA is inspiring. Despite the challenges, he continues to serve with grit and determination, ensuring the smooth operation of the VLA. His story serves as a reminder that with passion and dedication, one can achieve great heights in any field.

When seen in the optical, Saturn's banded atmosphere appears to smoothly shift from color to color. But seen here in radio light, the distinct nature of these bands is apparent. Scientists used VLA data to better understand ammonia in the gas giant's atmosphere and learned that megastorms transport the ammonia from the upper to the lower atmosphere.
VLA Finds Megastorms on Saturn Disrupt Gas Giant’s Deep Atmosphere in Surprising Ways
August 11, 2023 at 2:00 pm | Tip Sheet

A study of rare megastorms on Saturn using data from the National Science Foundation’s Karl G. Jansky Very Large Array has revealed disruptions in the distribution of ammonia gas in the planet’s deep atmosphere. The findings raise questions about just how different gas giants can be from each other, and challenge scientists’ understanding of how megastorms may form on planets other than Earth.
