Four new exoplanets discovered by young astronomers still in high school

Just in case you were feeling complacent about your achievements lately: A pair of high schoolers involved in a mentorship program at Harvard have helped to discover four new exoplanets. As co-authors on a peer-reviewed paper in the Astronomical Journal, they are some of the youngest published astronomers ever.

16-year-old Kartik Pinglé and 18-year-old Jasmine Wright worked on data from NASA’s Transiting Exoplanet Survey Satellite (TESS), looking particularly at a nearby star called TOI 1233. By looking for dips in brightness from stars, researchers can identify exoplanets passing between us and the star. In this case, the team found no less than four planets in orbit.

“I was very excited and very shocked,” Wright said in a statement. “We knew this was the goal of [mentor Tansu] Daylan’s research, but to actually find a multi-planetary system, and be part of the discovering team, was really cool.”

The system consists of a star orbited by three sub-Neptunes, which are gaseous planets like Neptune but smaller, which have orbits of between six and 19.5 days each. The fourth planet is a super-Earth, meaning it is rocky like our planet but larger, which orbits the star every four days.

Mentor Tansu Daylan says he hopes to study this system in greater detail, and that it could help researchers understand more about how systems form.

“Our species has long been contemplating planets beyond our solar system and with multi-planetary systems, you’re kind of hitting the jackpot,” he said in the statement. “The planets originated from the same disk of matter around the same star, but they ended up being different planets with different atmospheres and different climates due to their different orbits. So, we would like to understand the fundamental processes of planet formation and evolution using this planetary system.”

Daylan also said he valued having young astronomers in his group as they bring a fresh perspective. “As a researcher, I really enjoy interacting with young brains that are open to experimentation and learning and have minimal bias,” he said. “I also think it is very beneficial to high school students since they get exposure to cutting-edge research and this prepares them quickly for a research career.”

This could be just the beginning of an astronomy career for the two promising young researchers. Pinglé is considering studying applied mathematics or astrophysics once he graduates, and Wright will soon be starting a Master’s program in astrophysics.

How astronomers used James Webb to detect methane in the atmosphere of an exoplanet

An artists rendering of a blue and white exoplanet known as WASP-80 b, set on a star-studded black background. Alternating horizontal layers of cloudy white, grey and blue cover the planets surface. To the right of the planet, a rendering of the chemical methane is depicted with four hydrogen atoms bonded to a central carbon atom, representing methane within the exoplanet's atmosphere. An artist’s rendering of the warm exoplanet WASP-80 b whose color may appear bluish to human eyes due to the lack of high-altitude clouds and the presence of atmospheric methane identified by NASA’s James Webb Space Telescope, similar to the planets Uranus and Neptune in our own solar system.

One of the amazing abilities of the James Webb Space Telescope is not just detecting the presence of far-off planets, but also being able to peer into their atmospheres to see what they are composed of. With previous telescopes, this was extremely difficult to do because they lacked the powerful instruments needed for this kind of analysis, but scientists using Webb recently announced they had made a rare detection of methane in an exoplanet atmosphere.

Scientists studied the planet WASP-80 b using Webb's NIRCam instrument, which is best known as a camera but also has a slitless spectroscopy mode which allows it to split incoming light into different wavelengths. By looking at which wavelengths are missing because they have been absorbed by the target, researchers can tell what an object -- in this case, a planetary atmosphere -- is composed of.

Astronomers spot the shiniest exoplanet ever discovered

An artist impression of exoplanet LTT9779b orbiting its host star.

When you look up at the night sky you see mostly stars, not planets -- and that's simply because planets are so much smaller and dimmer than stars. But you can see planets in our solar system, like Venus, which is one of the brightest objects in the night sky. Due to its thick, dense atmosphere, Venus reflects 75% of the sun's light, making it shine brightly. Recently, though, astronomers discovered a planet that reflects even more of its star's light, making it the shiniest exoplanet ever found.

Exoplanet LTT9779 b reflects 80% of the light from its star, which it orbits very close to. That makes it extremely hot, and researchers believe that the planet is covered in clouds of silicate and liquid metal, which is what makes it so reflective.

Astronomers spot an exoplanet creating spiral arms around its star

The Large Binocular Telescope in Arizona. The LBTI instrument combines infrared light from both 8.4-meter mirrors to image planets and disks around young and nearby stars.

When you imagine a galaxy like our Milky Way, you're probably picturing a swirl shape with arms reaching out from a central point. These spiral arms are a classic feature of many galaxies. Similar structures can be found around young stars which are surrounded by disks of matter from which planets form, called protoplanetary disks. Now, astronomers have discovered evidence that these structures could be created by recently formed exoplanets.

Astronomers used Large Binocular Telescope in Arizona to investigate a giant exoplanet named MWC 758c which seems to be forming the spiral arms around its host star. Located 500 light-years away, the star is just a few million years old, making it a baby in cosmic terms. "Our study puts forward a solid piece of evidence that these spiral arms are caused by giant planets," said lead researcher Kevin Wagner of the University of Arizona in a statement. "And with the new James Webb Space Telescope, we will be able to further test and support this idea by searching for more planets like MWC 758c."
