In 2023, the James Webb Space Telescope (JWST) helped identify hundreds of free-floating "rogue" planets that don't orbit a parent star. Now, astronomers have found that a pair of these planets may be producing enigmatic, hard-to-interpret radio signals.

The rogue planets spotted by JWST lie in the Orion Nebula, a long-time observational hotspot for astronomers. In total, they number over 500. This discovery bonanza was possible thanks to JWST's ability to pick up infrared radiation emitted by these relatively young planets.

Bizarrely, though, about 80 of these planets exist as pairs. Similar in mass to Jupiter, the planets orbit each other at distances ranging from 25 to 400 times the distance between Earth and the sun. These tangoing duos, called Jupiter-mass binary objects (JuMBOs), pose a huge mystery for astronomers, because the existence of these worlds challenges current theories of planet formation. Some scientists think these objects may not even be planets but rather previously unknown entities that are larger than planets but smaller than brown dwarfs, which are sometimes called "failed stars" because they blur the line between planets and stars.

The JWST data showed that JuMBOs generated infrared radiation, but the new study's authors wanted to see if these dancing objects produced radio waves. That's because different classes of cosmic objects produce distinct patterns of radio emissions. For instance, planets like Jupiter spew several types of radio signals, including gigahertz-frequency emissions thousands of times higher-pitched than an FM signal, partly because of their magnetic fields.

Spotting such signatures from the JuMBOs could help resolve their identity. The observations could also explain "why some objects have detectable radio emission and others do not," lead study author Luis Rodríguez, a professor emeritus at the Institute of Radio Astronomy and Astrophysics at the National Autonomous University of Mexico, told Live Science in an email.

To find radio wave "snapshots" of the Orion Nebula where the JuMBOs reside, the scientists combed through archives of observations maintained by the U.S. National Radio Astronomy Observatory (NRAO). They found just one pair that apparently emits radio waves: JuMBO 24. Itself an oddity among the oddball objects, it's the heaviest of the JuMBOs, and also the one with the tightest space between its component planets.

A decade's worth of data the research team collated showed that the radio waves remained steady but strong, with a power of roughly a quarter of a ton of TNT and frequencies of 6 to 10 gigahertz. The radio waves also weren't circularly polarized, meaning they lacked spiral, twisting electric fields, the team reported in their study, published Jan. 8 in The Astrophysical Journal Letters.

But these features aren't what astronomers expect of signals created by planets." Circular polarization is an unambiguous indicator of the presence of magnetic fields," Rodríguez said. Without this, the team can't say definitively that the signals come from JuMBO 24 (assuming the planets have magnetic fields). Besides, radio emissions from other exoplanets are more variable and less intense.

Even if JuMBO 24 isn't a pair of planets but rather another type of cosmic duo, the signals are unusual. Signals from brown dwarfs are very different from the newly identified radio beams. The beams' brightness and frequency even ruled out the possibility of pulsars, the rapidly spinning cores of dead stars that produce pulses of radio waves at regular intervals.

The researchers also estimated the likelihood that the signals originate from an object behind JuMBO 24 and found it to be exceedingly slim, at just 1 in 10,000. And, in case you were wondering, the signals probably don't originate from aliens.  "The fact that both components emit at similar levels favors a natural mechanism," Rodríguez said.

With the research at an impasse, the team is applying to the NRAO's Very Large Array in New Mexico to collect data from free-floating planets. Until then, the radio signals will remain a mystery.

The tasty tomatillo (Physalis philadelphica) is where we get the English name “tomato”. The tomatillo is a domesticated version of wild plants found in Central America and is known in the Nahuatl language as “tomatl”. This plant is related to tomatoes because it is a member of the Solanaceae family, but it is not a tomato! This fruit grows in a husk that resembles a paper lantern and when it’s ripe the husk splits to reveal the plump green fruit. The tomatillo is the main ingredient of Mexican / Tex Mex salsa verde.

Helia Bravo Hollis

Helia Bravo Hollis was born in Mexico City in 1901. Hollis was a botanist who devoted her career to the study of cacti. Her 1937 book Mexican Cacti established her reputation as one of the leaders in this field. Over the course of a 60-year career, Hollis published two books, nearly 170 articles, roughly 60 taxa descriptions and 59 taxonomic revisions. She was co-founder and director of the Mexican Cactology Society and she helped establish UNAM's botanical garden.

Helia Bravo Hollis died in 2001 at the age of 99.

one night while pondering azian vance's history and personality and esteemed deeds i thought abt that one anecdote about how ann duryan and carl sagan fell in love while working on the voyager golden record and thought it'd be cute for them if they had a similar experience before signing on with black mesa. like, they got signed as a package deal, both of them up and coming physicists with some hot thesis on ok i think it'd be kind of sweet if it had to do with gravity somehow. that perhaps an early version of the gravity gun was imagined by the two of them, and black mesa was interested in it for its utility in handling hazardous materials. what if

Rafael Navarro-Gonzalez (1959-2021): The Mexican Astrobiologist Who Shaped Our Understanding of The Planet Mars

Rafael Navarro-Gonzalez was a talented and internationally recognized chemist and astrobiologist who worked at NASA. Navarro-Gonzalez is known for his work with other researchers to study the planet Mars. He made fundamental contributions to several fields related to Astrobiology, the origin of life, and life in extreme environments. Among his many accomplishments, he helped lead the team that identified ancient organic compounds on Mars. He was a Co-I on the SAM instrument onboard NASA’s Mars Science Laboratory and on the HABIT instrument onboard ESA’s ExoMars mission. He was also on the Curiosity Mars rover team. His research blended laboratory simulations, fieldwork, and theoretical modeling in transdisciplines in chemistry, physics, and biology. This sort of dominance is unusual and requires a dynamic and intellectual curiosity beyond normal boundaries. He identified the role of volcanic lightning in the origin of life on Earth. He has established one of the very best laboratories in Latin-America.

He has published 137 papers, 4 edited books and over 225 abstracts. Among the most significant contributions are those that deal the detection of organics in Mars-like environments from cold (Antarctica), temperate (Atacama) and hot (Mojave and Libya) deserts on Earth.

Navarro-Gonzalez was born in Mexico City on April 25, 1959. He earned a bachelor’s in biology from the National Autonomous University of Mexico (UNAM) where he became full professor in 2002, and a PhD in Chemistry from the University of Maryland at College Park. Dr. Navarro-González established the Laboratory of Plasma Chemistry and Planetary Studies of the Institute of Nuclear Science at UNAM. 

Rafael Navarro-Gonzalez was the first recipient of the Molina fellowship award. This prize recognizes outstanding scientific achievement. He was also the recipient of the 2009 Alexander von Humboldt Medal and the World Academy of Sciences Award in Earth Sciences.

He died on Jan. 28, 2021 due to Covid-19-related complications.

In honor of his service, NASA named a mountain on Mars after him. The mountain stretches 450 feet (120 meters) tall, “Rafael Navarro Mountain” is located on Mount Sharp in northwest Gale Crater.

Rafael Navarro Mountain

“Rafael was a good friend and dedicated scientist, and it has been a privilege and honor for our Mars exploration team to work with him over the years" said the principal investigator of Curiosity’s SAM experiment.

“We are truly honored to have a prominent hill named after our dad; it’s his and our dream come true to see this happen,” wrote Navarro-González’s children, Rafael and Karina Navarro Aceves, in a statement to NASA.

“Our dad was an accomplished scientist, but above all, a great human being who managed to balance work and family."

Mexico has elected Claudia Sheinbaum as president. She’s an environmental scientist, a feminist and she’s Jewish.

She’s also anti-Zionist, which has led to a bunch of idiots on twitter saying she isn’t really Jewish. The evidence? She thanked Jesus in her acceptance speech.

…Her husband is called Jesús.

She was thanking her husband.

Edit: An update on this one folks. Reading a lot of what Mexicans have written in the notes, there’s a whole lot to criticise about Claudia Sheinbaum.

While that doesn’t change anything about idiots on twitter invalidating her Jewishness, the top of this post was far too complimentary.

got to the Midnight Burger interludes they were so good

I love how so far in the series as a whole there are no big plot twists big reveals, everything is set pretty clearly from the start, the most shocking plot twists aren't that there are interdimensional creatures it's the super mundane everyday life tragedies in the lives of the crew

also love that there aren't big treasons, people just suck, and they make shitty decisions because they suck, and because they think they are right but they suck in normal mundane ways

I was waiting for the other shoe to drop and some characters to go surprise! I was evil all along!!! but no, you're presented with the characters as they are and it's all pretty plain to see, no big plot twists no big betrayals, it all makes sense and sometimes, it sucks bc things are going the only way they could've gone bc people kind of suck

but also there's a diner that appears for people with nowhere to go because someone out there had a plan and didn't want a stranger to be alone
