Radio on Jupiter, Brought to You by Ganymede

Louis et al. [2020] present exciting new observations of radio emissions on Jupiter from the NASA Juno spacecraft – the first direct detection of Jovian decametric radio emissions induced by the interaction between Jupiter and the moon Ganymede. These observations were made as Juno crossed a polar region of the Giant Planet where […]

Now-dead radio telescope finds bizarre venomous-spider star

Astronomers have discovered black widows and redbacks in space. While these cosmic objects don’t kill and eat their mates, the stars share their eight-legged counterparts’ violent behavior toward companions. In addition to the run-of-the-mill spider stars, the researchers also discovered a bizarre black widow-redback crossbreed. The scientists used the now-destroyed Arecibo telescope in Puerto Rico […]

Astronomers are still reeling from the loss of iconic Arecibo radio telescope

The collapse of the iconic radio telescope at the Arecibo Observatory in Puerto Rico last month has left astronomers with a host of questions about what went wrong and what comes next. During a virtual town hall event held at the 237th conference of the American Astronomical Society on Monday (Jan. 11), officials at the […]

Earthlings and astronauts chat away, via ham radio

Credit: CC0 Public Domain The International Space Station cost more than $100 billion. A ham radio set can be had for a few hundred bucks. Perhaps that explains, in part, the appeal of having one of humankind’s greatest scientific inventions communicate with Earth via technology that’s more than 100 years old. But perhaps there’s a […]

Scientists complete yearlong pulsar timing study after reviving dormant radio telescopes

While the scientific community grapples with the loss of the Arecibo radio telescope, astronomers who recently revived a long-dormant radio telescope array in Argentina hope it can help modestly compensate for the work Arecibo did in pulsar timing. Last year, scientists at Rochester Institute of Technology and the Instituto Argentino de Radioastronomi­a (IAR) began a […]

China is opening the world’s largest radio telescope up to international scientists

Following the collapse of the historic Arecibo Observatory in Puerto Rico, China has opened the biggest radio telescope in the world up to international scientists.  In Pingtang, Guizhou province stands the Five-hundred-meter Aperture Spherical Telescope (FAST), the largest radio telescope in the world, surpassing the Arecibo Observatory, which stood as the largest in the world […]

Scientists think they’ve detected radio emissions from an alien world

Scientists may have detected radio emissions from a planet orbiting a star beyond our sun for the first time. The astronomers behind the new research used a radio telescope in the Netherlands to study three different stars known to host exoplanets. The researchers compared what they saw to observations of Jupiter, diluted as if being […]

Astronomers detect possible radio emission from exoplanet — ScienceDaily

By monitoring the cosmos with a radio telescope array, an international team of scientists has detected radio bursts emanating from the constellation Boötes — that could be the first radio emission collected from a planet beyond our solar system. The team, led by Cornell postdoctoral researcher Jake D. Turner, Philippe Zarka of the Observatoire de […]

FM Radio on Jupiter, Brought to You by Ganymede

Louis et al. [2020] present exciting new observations of radio emissions on Jupiter from the NASA Juno spacecraft – the first direct detection of decametric radio emissions originating from its Moon Ganymede. These observations were made as Juno crossed a polar region of the Giant Planet where the magnetic field lines are connected […]

Huge Puerto Rico radio telescope collapses; many mourning

This satellite image provided by 2020 Maxar Technologies shows the damaged radio telescope at the Arecibo Observatory in Puerto Rico, Thursday, Nov. 17, 2020. The National Science Foundation announced Thursday, Nov. 17 that it will close the huge telescope in a blow to scientists worldwide who depend on it to search for planets, asteroids and […]
