Hot Jupiter Endures Star-Powered Barbecue

June 24, 2026

You’re the grillmaster at the annual family 4th of July BBQ and you’re sweating bullets standing over the grill in the sweltering summer heat. You’re trying to stay cool by pressing a cold beer can on your forehead, but to no avail. You can’t go inside because, once again, you’re the grillmaster and need to watch the food simmering on your freshly cleaned grill. Your brother-in-law is a university astronomy professor and walks over asking how you’re doing. You say, “This heat is killing me. I feel hotter than the barbeque!” Your science teacher brother-in-law slyly says, “Try being an exoplanet.” You roll your eyes.

Lava planet has hydrogen-rich, active atmosphere

June 17, 2026

It’s 2158, and you’re chugging away on your PhD in Planetary Volcanology from the University of Utopia Planitia on Mars. Graduate students still get paid a sub-living wage, so you’ve been stuck eating freeze-dried ramen for the past three years. You’ve completed studying Jupiter’s moon, Io, but now you have to leave the solar system for a good exoplanet analog. While Io’s volcanism is caused by tidal heating, you need an exoplanet whose volcanism is caused by extreme heat from its host star. You recently secured funding from the Exoplanet Research Institute for a faster-than-light (FTL) ship, but the exoplanet is required to be less than 50 light-years away.

JWST Finds Exoplanets Choked by Diesel Smog

June 13, 2026

It’s 2134, and humanity has finally embraced green technologies while ridding the Earth of harmful fossil-burning technologies, most notably gasoline, wood, coal, and oil. As a result, soot has been rendered obsolete, and all commercial products from soot, including shoes, wires, computer products, and eye products, are now produced from eco-friendly technologies. However, the uber-rich who still fancy non-eco-friendly products are willing to pay soot’s weight in gold for it. Therefore, the Exoplanet Research Corporation outfits its best ship to search for soot-enriched exoplanet atmospheres.

Longest-period young transiting exoplanets discovered

June 01, 2026

It’s 2234, you’re on your annual class field trip touring exoplanets, and your teacher informs everyone they can pick one more exoplanetary system to explore before heading back to Earth. You and your classmates are exhausted from the day’s activities and you’re hungry. However, you get really excited because you already know what everyone will want. You and your classmates all shout in unison, “The young and far away puffy ones!”

Roman Telescope's massive infrared mirror is ready to fly

June 01, 2026

It’s June 2027, and you’re fresh off defending your PhD studying the direct imaging of exoplanets while starting your postdoctoral journey at NASA Jet Propulsion Laboratory. The trauma of eating ramen and living off a sub-living wage for the last five years of your life is still fresh in your brain. But you’re excited to finally get your real career started with funding you received for viewing time on the much-anticipated Nancy Grace Roman Space Telescope (Roman for short). You begin to download the first set of data as your eyes tear up knowing your entire journey in research and academia is about to be worth it.

JWST Finds Methane Atmosphere on Temperate Exoplanet

June 01, 2026

It’s 2165, and methane is in high demand, especially after the Titan Treaty of 2145 made it illegal to harvest methane from Saturn’s moon, Titan. But the advent of interstellar travel has made exoplanetary exploration far easier, enabling corporations to identify and harvest methane from exoplanets. However, it’s far cheaper and easier to harvest methane from exoplanets with reasonable (also called temperate) temperatures, because it means higher quantities of methane. The Exoplanet Exploration Corporation decides to send its first ship to one such exoplanet loaded with methane that could bring their quarterly financial statements back into the green.

MAVEN Spacecraft Finds New Plasma Squeezing at Mars

May 30, 2026

A cloaked alien invasion force is approaching Earth and coming up on Mars. The first officer looks through a viewfinder and says, “Captain, the fourth planet’s atmosphere is behaving strangely. As though it were trying to block incoming energy.” The captain takes a moment, then his (already big) eyes get wide and he exclaims, “It’s a defense shield! The Earthlings are hiding on the fourth planet and are prepared to attack us! Abort the invasion!” The first officer responds, “Aye aye, Captain!”

NASA TESS Reveals Epic All-Sky Map of Distant Worlds

May 27, 2026

You’re on a camping trip with your family and your parents tell you to turn off all the lights. But, of course, your little brother wants to shine his flashlight directly at the sky saying aliens will see it. You finally get him to shut off his flashlight, and you give your eyes a few minutes to adjust to the darkness. As they do, more and more stars begin to appear in the night sky that were initially hidden beneath the glare of your (loser) brother’s flashlight. As the stars get brighter and increase in number, you start firing off a slew of questions in your head: How far away are they? Are there planets around them? What kinds of life are on those planets?

Alien life may be missed by current space missions, but AI might help

May 24, 2026

It’s 2035 and NASA’s Dragonfly quadcopter has been “hopping” around the surface of Saturn’s largest moon Titan for just over a year taking images, scanning pebbles, drilling holes, and analyzing surface material for potential signs of life. You’re at NASA JPL and just moved to Blue Team (12am-8am) from Red Team (4pm-12am), so you’re hyped up on coffee, Red Bull, and will power. It’s 3:30am, you’ve been analyzing data since you clocked in, and you keep discarding what you’ve been told looks like positive signs of life but is more commonly known as false positives. In the meantime, some microbes on Titan that got scanned by Dragonfly keep posing in front of its main camera with signs saying, “We’re here!”

Mars Fungi Could Make Red Planet Regolith Fertile for Crops

May 23, 2026

You’re on the fourth human mission to Mars, and you’ve been tasked with establishing the first self-sustaining food crop on a Martian settlement. You’re nervous because you’re using a new type of fungi called beneficial fungi, which you’re told will help enhance Martian regolith, enabling it to be used for growing crops. You were privately told that doing this will not only get a high school named after you, but you will successfully feed future settlers without the need to bring food from Earth. But you really only care about having your name on a high school.

TESS Data Reveals 27 New Planet Candidates in Binary Systems

May 19, 2026

You’re doing some late afternoon work on the habitat as part of humanity’s first exoplanet settlement, but the sun is going down so you’re trying to speed things up. Just as the light dims, everything suddenly starts getting brighter. You look up and see the sun starting to rise again, except it’s your second sun. You kick yourself for not checking the daily sunrise and sunset logs, but you’re happy you get to put in a bit more work before you eat dinner.

Were Martian Tides Strong Enough to Shape its Ancient Landscape?

May 13, 2026

You’re an anaerobic microbe sunbathing on a Martian beach billions of years ago listening to the small waves hit the shoreline as you take in the perchlorates in the Martian regolith. This is because while Mars is warm and wet, it still lacks sufficient oxygen, so anaerobic life like yourself doesn’t need oxygen to survive. You’re chilling for several hours and eventually notice the water hasn’t touched you. You remember over-hearing some otherworldly fellows who briefly landed and discussed the landscape didn’t look well formed, so they left.

Saturn’s Icy Rings Likely Formed from Lost Moon "Chrysalis"

May 09, 2026

You’re a long-necked Titanosaurs grazing the plains and chomping away on tree leaves about 100 million years ago in the Early Cretaceous in what would eventually become a future Starbucks location. You look up at the night sky and notice a bright dot that seems slightly larger and brighter than usual since you’ve seen it a bunch. You grunt at your cousin (official dinosaur language) asking if he notices it, too. Your cousin grunts back that it does seem bigger and brighter and wonders what’s up.

New Lithium-Plasma Engine Passes Key Mars Propulsion Test

May 01, 2026

You’re on the fourth human mission to Mars, and you’re told the Odyssey spacecraft designed to take you there will be the smoothest ride you’ll ever take. It features a newly christened electric propulsion engine which was in the late stages of testing during the first three missions. The mission starts and the spacecraft travels at a crawl, and you wonder if it’s broken. A week goes by and you’re now traveling at more than 400,000 kilometers (250,000 miles) per hour, and your mind is blown as to how fast you’re going, how quickly that happened, and that this mission might be more awesome than you thought.

Flexible 3D-Printable Shielding for Extreme Environments

April 30, 2026

You’re based at Artemis Station on the lunar south pole, and you’re monitoring your 12 autonomous rovers that are exploring the surrounding terrain for signs of water ice or other essentials minerals. They’re about 3 kilometers out when you suddenly get a NASA Alert for an incoming solar storm. You know the rovers won’t return to base before the storm hits, but you’re calm knowing the rovers all recently got retrofitted with the latest hair-thin nanotube shielding to protect them from the harsh electromagnetic waves and radiation.

Canada Proposes POET Mission to Hunt Earth-Sized Planets

April 29, 2026

Exoplanet science and the search for life beyond Earth continue to advance at break-neck speeds, with the number of confirmed exoplanets by NASA rapidly approaching 6,300, with 223 of those exoplanets being designated as terrestrial (rocky) exoplanets. With the promise of discovering an increasing number of Earth-sized exoplanets increasing every day, new telescopes from across the world have the opportunity to contribute to this incredible field.

Designing In Situ Power Stations for Future Mars Missions

April 29, 2026

You’re in the lab analyzing Martian regolith samples within your cozy Mars habitat serving on fifth human mission to Mars. The power within the habitat has been flowing flawlessly thanks to the MARS-MES (Mars Atmospheric Resource & Multimodal Energy System), including the general habitat lighting, science lab, sleeping quarters, exercise equipment, the virtual reality headsets the crew use for rest & relaxation, oxygen and fuel generation, and water. All this from converting the Martian atmosphere into workable electricity.

Space Travel May Impact Human Fertility and Fertilization

April 28, 2026

Space travel has taught us valuable lessons for living and working in outer space, specifically regarding how microgravity (often mistakenly called zero-gravity) impacts the human body during short- and long-term spaceflight. This includes decreased muscle and bone mass, fluid shifts, reduced heart rate, psychological health, compromised immune system, and radiation exposure. But with agencies like NASA aspiring to build a lunar base and establish a long-term presence on the Moon, and eventually Mars, how could space travel impact potentially having babies in space?

Webb Finds Water-Ice Clouds on Nearby Super-Jupiter

April 26, 2026

The giant planets in our solar system—Jupiter, Saturn, Uranus, and Neptune—have challenged our understanding of planetary formation and evolution. Specifically, their atmospheric formations and compositions have provided awe-inspiring images from spacecraft and given scientists key insights into the interior mechanisms of these massive worlds. But what about exoplanets? What can their atmospheres teach scientists about their formation, evolution, composition, and interior mechanisms? And how do longstanding exoplanet models stack up against the real thing?

TOI-201 Planets Are Wobbling Out of Our Line of Sight

April 25, 2026

It turns out that even after studying our solar system in depth and discovering more than 6,100 exoplanets across more than 4,500 exoplanetary systems, not all solar systems are created equal. The longstanding notion is that planets orbit almost entirely in the same orbital path, also called an orbital plane. But what if an exoplanetary system was found to have exoplanets that not only orbit in different planes, but also exhibits changing behavior regarding when they pass in front of their star?
