The Allen Telescope Array in California detected signal from the Voyager 1 probe, the NASA satellite tv for computer launched 45 year ago that’s currently speeding in direction of the outer edges of the solar design, manner beyond the orbit of Pluto. 

Allen Telescope Array (ATA), a no longer too long ago refurbished radio observatory shut to San Francisco in California dedicated to the look for extraterrestrial life, made contact with the Voyager 1 probe on July 9, utilizing 20 of its 42 dish antennas, which are each over 20 toes (6.1 meters) broad. The telescope recorded 15 minutes of files, in accordance to a commentary (opens in new tab), which were saved on a disk. 

“The detection of Voyager 1, the farthest human-made object, with the refurbished Allen Telescope Array is an out of this world expose of the telescope’s capabilities and strengths, and a illustration of the famed laborious work set by the ATA team for the reason that open of the refurbishment program in 2019,” the team mentioned within the commentary.

The commentary did not present any extra files referring to the signal it caught. NASA has been investigating a involving glitch that has brought about Voyager 1 to ship help nonsense files about its plan in residence. NASA first reported the glitch in Might perchance perchance well additionally, though it has no longer specified when the train began. The agency is confident the spacecraft is loyal because if the gibberish files were simply, the signal from Voyager 1 would no longer be wisely pointed in direction of Earth.

For the time being positioned about 14.5 billion miles (23.3 billion kilometers) away from Earth, 156 instances the solar-Earth distance, Voyager 1 is still being tracked by NASA’s Deep Home Network, sending a meager 160 bits per 2d of files help residence. For comparison, a regular residence broadband connection is measured in megabits per 2d, that’s millions of bits per 2d.

The spacecraft, which entered what astronomers clarify as interstellar residence 10 years ago, is measuring properties of the interstellar medium beyond the perimeter of the heliosphere, the bubble of plasma created by the solar that surrounds the planets.

Voyager 1 still has to cruise via the Oort Cloud, a spherical disc of comets and asteroids on the farthest reaches of the solar design, greater than 200 solar-Earth distances away from the solar. 

No spacecraft has ever visited the Oort Cloud and Voyager 1 will purchase about 300 years to earn there. By then, nevertheless, the probe will long be needless because it be anticipated to flee out of fuel to energy its programs as early as 2025.
