Webb Detects Tiny Quartz Crystals in the Clouds of a Hot Gas Giant Researchers using NASA’s James Webb Space Telescope have detected evidence for quartz nanocrystals in the high-altitude clouds of WASP-17 b, a hot Jupiter exoplanet 1,300 light-years from Earth. The detection, which was uniquely possible with MIRI (Webb’s Mid-Infrared Instrument), marks the first time that silica (SiO2) particles have been spotted in an exoplanet atmosphere. This artist concept shows what the exoplanet WASP-17 b could look like. Graphics: NASA, ESA, CSA, and R. Crawfor, d (STScI)Science: Nikole Lewis (Cornell University), David Grant (University of Bristol), Hannah Wakeford (University of Bristol) Crawford (STScI) “We were thrilled!” said David Grant, a researcher at the University of Bristol in the UK and first author on a paper being published today in the Astrophysical Journal Letters. “We knew from Hubble observations that there must be aerosols—tiny particles making up clouds or haze—in WASP-17 b’s atmosphere, but we didn’t expect them to be made of quartz.” Silicates (minerals rich in silicon and oxygen) make up the bulk of Earth and the Moon as well as other rocky objects in our solar system, and are extremely common across the galaxy. But the silicate grains previously detected in the atmospheres of exoplanets and brown dwarfs appear to be made of magnesium-rich silicates like olivine and pyroxene, not quartz alone – which is pure SiO2. The result from this team, which also includes researchers from NASA’s Ames Research Center and NASA’s Goddard Space Flight Center, puts a new spin on our understanding of how exoplanet clouds form and evolve. “We fully expected to see magnesium silicates,” said co-author Hannah Wakeford, also from the University of Bristol. “But what we’re seeing instead are likely the building blocks of those, the tiny ‘seed’ particles needed to form the larger silicate grains we detect in cooler exoplanets and brown dwarfs.” Detecting Subtle Variations With a volume more than seven times that of Jupiter and a mass less than one-half Jupiter, WASP-17 b is one of the largest and puffiest known exoplanets. This, along with its short orbital period of just 3.7 Earth-days, makes the planet ideal for transmission spectroscopy : a technique that involves measuring the filtering and scattering effects of a planet’s atmosphere on starlight. Webb observed the WASP-17 system for nearly 10 hours, collecting more than 1,275 brightness measurements of 5- to 12-micron mid-infrared light as the planet crossed its star. By subtracting the brightness of individual wavelengths of light that reached the telescope when the planet was in front of the star from those of the star on its own, the team was able to calculate the amount of each wavelength blocked by the planet’s atmosphere. What emerged was an unexpected “bump” at 8.6 microns, a feature that would not be expected if the clouds were made of magnesium silicates or other possible high temperature aerosols like aluminum oxide, but which makes perfect sense if they are made of quartz. A transmission spectrum of the hot gas giant exoplanet WASP-17 b captured by Webb’s Mid-Infrared Instrument (MIRI) on March 12-13, 2023, reveals the first evidence for quartz (crystalline silica, SiO2) in the clouds of an exoplanet. The spectrum was made by measuring the change in brightness of 28 wavelength-bands of mid-infrared light as the planet transited the star. Webb observed the WASP-17 system using MIRI’s low-resolution spectrograph for nearly 10 hours, collecting more than 1,275 measurements before, during, and after the transit. For each wavelength, the amount of light blocked by the planet’s atmosphere (white circles) was calculated by subtracting the amount that made it through the atmosphere from the amount originally emitted by the star. The solid purple line is a best-fit model to the Webb (MIRI), Hubble, and Spitzer data. (The Hubble and Spitzer data cover wavelengths from 0.34 to 4.5 microns and are not shown on the graph.) The spectrum shows a clear feature around 8.6 microns, which astronomers think is caused by silica particles absorbing some of the starlight passing through the atmosphere. The dashed yellow line shows what that part of the transmission spectrum would look like if the clouds in WASP-17 b’s atmosphere did not contain SiO2. This marks the first time that SiO2 has been identified in an exoplanet, and the first time any specific cloud species has been identified in a transiting exoplanet. Graphics: NASA, ESA, CSA, and R. Crawfor, d (STScI)Science: Nikole Lewis (Cornell University), David Grant (University of Bristol), Hannah Wakeford (University of Bristol) Crawford (STScI) Download full resolution images for this article from the Space Telescope Science Institute (STScI) Crystals, Clouds, and Winds While these crystals are probably similar in shape to the pointy hexagonal prisms found in geodes and gem shops on Earth, each one is only about 10 nanometers across—one-millionth of one centimeter. “Hubble data actually played a key role in constraining the size of these particles,” explained co-author Nikole Lewis of Cornell University, who leads the Webb Guaranteed Time Observation (GTO) program designed to help build a three-dimensional view of a hot Jupiter atmosphere. “We know there is silica from Webb’s MIRI data alone, but we needed the visible and near-infrared observations from Hubble for context, to figure out how large the crystals are.” Unlike mineral particles found in clouds on Earth, the quartz crystals detected in the clouds of WASP-17 b are not swept up from a rocky surface. Instead, they originate in the atmosphere itself. “WASP-17 b is extremely hot—around 1,500 degrees Celsius (2,700°F)—and the pressure where they form high in the atmosphere is only about one-thousandth of what we experience on Earth’s surface,” explained Grant. “In these conditions, solid crystals can form directly from gas, without going through a liquid phase first.” Understanding what the clouds are made of is crucial for understanding the planet as a whole. Hot Jupiters like WASP-17 b are made primarily of hydrogen and helium, with small amounts of other gases like water vapor (H2O) and carbon dioxide (CO2). “If we only consider the oxygen that is in these gases, and neglect to include all of the oxygen locked up in minerals like quartz (SiO2), we will significantly underestimate the total abundance,” explained Wakeford. “These beautiful silica crystals tell us about the inventory of different materials and how they all come together to shape the environment of this planet.” Exactly how much quartz there is, and how pervasive the clouds are, is hard to determine. “The clouds are likely present along the day/night transition (the terminator), which is the region that our observations probe,” said Grant. Given that the planet is tidally locked with a very hot day side and cooler night side, it is likely that the clouds circulate around the planet, but vaporize when they reach the hotter day side. “The winds could be moving these tiny glassy particles around at thousands of miles per hour.” WASP-17 b is one of three planets targeted by the JWST-Telescope Scientist Team’s Deep Reconnaissance of Exoplanet Atmospheres using Multi-instrument Spectroscopy (DREAMS) investigations, which are designed to gather a comprehensive set of observations of one representative from each key class of exoplanets: a hot Jupiter, a warm Neptune, and a temperate rocky planet. The MIRI observations of hot Jupiter WASP-17 b were made as part of GTO program 1353. The James Webb Space Telescope is the world’s premier space science observatory. Webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and the Canadian Space Agency.

All four RS-25 engines have been installed onto the SLS (Space Launch System) core stage for NASA’s Artemis II mission. The installation of the engines signals the core stage is nearly finished with assembly and will soon be ready for shipment to NASA’s Kennedy Space Center in Florida. During launch, the rocket’s engines provide more than two million pounds of combined thrust.Credits: NASA By Megan Carter NASA and its partners have fully secured the four RS-25 engines onto the core stage of the agency’s SLS (Space Launch System) rocket for the Artemis II flight test. The core stage, and its engines, is the backbone of the SLS mega rocket that will power the flight test, the first crewed mission to the Moon under Artemis. Engineers have begun final integration testing at NASA’s Michoud Assembly Facility in New Orleans, in preparation for acceptance ahead of shipment of the stage to Kennedy Space Center in Florida in the coming months. “NASA integrated many lessons learned from the first-time build and assembly of the SLS core stage for Artemis I to increase efficiencies during manufacturing and cross-team collaboration with our partners for Artemis II. NASA teams in New Orleans remain focused on assembling and preparing the SLS rocket’s liquid-fueled stage to support the flight.” Julie Bassler Manager of the Stages Office for the SLS Program “NASA integrated many lessons learned from the first-time build and assembly of the SLS core stage for Artemis I to increase efficiencies during manufacturing and cross-team collaboration with our partners for Artemis II,” said Julie Bassler, manager of the Stages Office for the SLS Program at the agency’s Marshall Space Flight Center in Huntsville, Alabama, where the program is managed. “NASA teams in New Orleans remain focused on assembling and preparing the SLS rocket’s liquid-fueled stage to support the flight.” The 212-foot-tall core stage includes two massive liquid propellant tanks and four RS-25 engines at its base. For Artemis II, the core stage and its engines act as the powerhouse of the rocket, providing more than two million pounds of thrust for the first eight minutes of flight to send the crew of four astronauts inside NASA’s Orion spacecraft on an approximately 10-day mission around the Moon. NASA, Aerojet Rocketdyne, an L3Harris Technologies company and the RS-25 engines lead contractor, along with Boeing, the core stage lead contractor, secured the engines to the maze of propulsion and avionics systems within the core stage Oct. 6. In the coming weeks, engineers will perform testing on the entire stage and its avionics and electrical systems, which act as the “brains” of the rocket to help control it during flight. Once testing of the stage is complete and the hardware passes its acceptance review, the core stage will be readied for shipping to Kennedy via the agency’s Pegasus barge, based at Michoud. The Artemis II RS-25 engines installed on the core stage at NASA’s Michoud Assembly Facility in New Orleans. Each engine is the size of a compact car and, together, will create more than two million pounds of thrust during launch. The RS-25 engines create immense pressure that controls the flow of liquid hydrogen and liquid oxygen from the two propellant tanks into each engine’s combustion chamber.Credits: NASA The Artemis II RS-25 engines installed on the core stage at NASA’s Michoud Assembly Facility in New Orleans.

The engines were first soft mated one by one onto the stage beginning in early September. The last RS-25 engine was structurally installed onto the stage Sept. 20. Installing the four engines is a multi-step, collaborative process for NASA, Boeing, and Aerojet Rocketdyne. Following the initial structural connections of the individual engines, securing and outfitting all four engines to the stage is the lengthiest part of the engine assembly process and includes securing the thrust vector control actuators, ancillary interfaces, and remaining bolts before multiple tests and checkouts. All major hardware elements for the SLS rocket that will launch Artemis II are either complete or in progress. The major components for the rocket’s two solid rocket boosters are at Kennedy. The rocket’s two adapters, produced at Marshall, along with the rocket’s upper stage, currently at lead contractor United Launch Alliance’s facility in Florida near Kennedy, will be prepared for shipment in the spring. NASA is working to land the first woman and first person of color on the Moon under Artemis. SLS is part of NASA’s backbone for deep space exploration, along with Orion and the Gateway in orbit around the Moon, and commercial human landing systems. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single mission.
