Radio Signals From Space

On November 6, 2024, sunspot AR 3883 unleashed a powerful X2.3 solar flare, causing radio blackouts in parts of South America and Africa. The flare, classified as a strong solar event, disrupted high-frequency radio signals. Scientists are awaiting data from NASA’s SOHO spacecraft to assess the potential impact of a coronal mass ejection (CME) on...

Scientists at Penn State and the SETI Institute have developed a new method to search for interplanetary radio signals from planets in the TRAPPIST-1 system. Using the Allen Telescope Array, they scanned this system for nearly 28 hours but did not find evidence of alien communication. This project, however, has introduced a new way of detecting pot...

Elon Musk's Starlink satellites are causing significant disruption for astronomers worldwide. Scientists from the Netherlands, particularly the Netherlands Institute for Radio Astronomy (ASTRON), have reported that the growing network of Starlink satellites is interfering with radio waves used for vital space research. The satellites, designed to p...

Astronomers recently detected an extraordinary event – a deep space radio signal that took 8 billion years to reach Earth. The radio burst, named FRB 20220610A, is one of the most powerful and distant signals ever captured. Fast radio bursts (FRBs) like this are brief but incredibly strong, leaving scientists questioning their origins.

A powerful X1.3-class solar flare erupted from the sun on 12 September 2024, potentially boosting aurora visibility across the US this weekend. The flare, which caused a geomagnetic storm rated at G3, also disrupted radio signals in various regions. NOAA’s Space Weather Prediction Center is closely monitoring this solar activity as more flares ar...

The flare, originating from sunspot AR3738, occurred late Saturday night (July 13) at 10:34 p.m. EDT (0234 UT on July 14), and was captured in stunning detail by NASA's Solar Dynamics Observatory.

The experiment was made possible by the Deep Space Optical Communications (DSOC) tool which was travelling onboard NASA's Psyche spacecraft.

FRBs are immensely useful for studying the cosmos, from investigating the matter that makes up the universe, to even using them to constrain the Hubble constant the measure of how much the universe is expanding.

Their findings are published in the journal Nature Astronomy.

The findings have been published in Monthly Notices of the Royal Astronomical Society.

Researchers at Cambridge University have developed a method that allows detecting light from the earliest stars by peering through clouds of hydrogen. Astronomers have aimed to detect a signal that would be a thousand times weaker than other radio signals. Here, using a radio telescope to trace the signal would result in distortions in the observat...

Astronomers have detected a strange radio signal coming from another galaxy, nearly 3 billion light-years away from Earth. This is the second time ever that such a repeating signal was detected by scientists.

Chinese astronomers have detected repeated fast radio bursts (FRB), mysterious signals believed to be from a source about 3 billion light years from the Earth.

NASA is preparing to launch twin satellites this month that focus on how radio signals that pass through the Earth's upper atmosphere can be distorted.

The signal was like nothing Abel Mendez had ever seen. It had the same frequency as radio emissions from satellites, but it pulsed like it came from something much more distant. It appeared only when Mendez and his colleagues had their telescope pointed at a single star - an unassuming red dwarf called Ross 128 just 11 light-years away.
