This was absolutely a team effort. Thank you to my collaborators at the Naval Research Laboratory and Bucknell University!

All of this is only possible thanks to the ongoing VLA Low-band Ionosphere Transient Experiment (VLITE; vlite.nrao.edu), led by the Naval Research Laboratory for over a decade. 📡

These guys are nearby at only about 5 parsecs (17 light-years), and there’s potential to dig in further with focused observations, now that we know they’re emitting at this frequency 🔭.

Intriguingly, these two stars are highly magnetically active (think solar flares, sunspots) ☀️, yet one of them might be rotating uncharacteristically slowly.

The magnetic interaction between Jupiter, its moons, and Io's plasma disk is analogous to what we might find in system with an ultracool dwarf system with exoplanets and a disk.

Part of the excitement is that we can use this frequency to search these cold objects for planets and disks of material that could go undetected at higher and lower frequencies 🌍. At the same time, we have a unique opportunity to learn about their magnetic properties! 🧲

Using an array of radio antennas in New Mexico, we found a pair of very small stars at a frequency which we’ve found no other “ultracool dwarfs” to-date. Ultracool dwarfs are the brown dwarfs and the least-massive stars, smaller than the Sun but bigger than a giant planet 🪐.

First Detection of an Ultracool Dwarf at 340 MHz: VLITE Observations of EI Cancri AB Magnetically driven phenomena such as flaring events and aurorae lead ultracool dwarfs to emit at radio frequencies. Despite decades of scrutiny, a comprehensive physical understanding of their radio ...

I’m excited to announce my latest astronomy research publication! 📝☀️📡

Buddy, I can see mountains reflected in the eyes of a trailside pika.

Congratulations Eliot!!! 💜

I got together with some mom friends tonight sans kids and we ate mac & cheese and made s'mores and talked about our gardens.

It's so nice to have casual friends you can unwind with every month or so. Busy or out of town this month? No worries, you can see them next month.

Sorry for your loss 🙁. A good reminder.

It’s like people forget that NASA has been through these ups and downs, developing processes and rigorous check systems to ensure mission safety and success. But no, we’re going to pay for rich billionaires’ pet projects to reinvent the wheel.

Gordon Stacey is great. He was my first research mentor back when I was an undergrad 🙂

Promising hints of life found on distant planet K2-18b Scientists find new but tentative evidence that a faraway world orbiting another star may be home to life.

An astonishing headline reporting on new observations from a team led to Nikku Madhusudhan claims they’ve found ‘hints of life’ on a planet orbiting a dwarf star some 124 light years away. What’s going on? (1/n) www.bbc.co.uk/news/article... 🔭 🧪

Trump and DOGE Are Planning Deregulation at a Massive Scale (Gift Article) The White House will soon move to rapidly repeal or freeze rules that affect health, food, workplace safety, transportation and more.

Even accepting the premise that AI produces useful writing (which no one should), using AI in education is like using a forklift at the gym. The weights do not actually need to be moved from place to place. That is not the work. The work is what happens within you.

“Many people don’t realize how high the American quality of life is because of the competent & stable enforcement of regulations, &if that goes away a lot of lives are at risk,” said Steve Cicala… “This affects airplane safety, baby formula safety, the safety of meat, vegetables and packaged foods…”

Why are the rare earths China is withholding so precious? China is blocking exports of these vital minerals. What makes them so special?

Museum and Planetarium Friends,

Many of you use NASA SVS material. Right now it is critical that we are able to document SVS's impact.

Please let us know how you are using our content (use my email address at the bottom of this page: svs.gsfc.nasa.gov).

Thank you!

So is this the time when we advise the people whom we have a duty of care not to go to the US for academic conferences?

Look you know you needed some feel-good news today.

Oh come ON now. This new JWST image is just ASTOUNDING.

I feel like I’m falling looking into it, and that I would fall forever, and that I would enjoy it.

It was an excellent talk on an important topic! Congratulations :)
