The James Webb Space Telescope (JWST) is a space telescope designed to conduct infrared astronomy. It is the largest telescope in space, and is equipped with high-resolution and high-sensitivity instruments, allowing it to view objects too old, distant, or faint for the Hubble Space Telescope. This enables investigations across many fields of astronomy and cosmology, such as observation of the first stars and the formation of the first galaxies, and atmospheric characterization of potentially habitable exoplanets. Despite Webb's mirror diameter being 2.7 times larger than that of the Hubble Space Telescope, it produces images of comparable resolution because it observes in the infrared spec…

The James Webb Space Telescope (JWST) is a space telescope designed primarily to conduct infrared astronomy. Its complex launch and commissioning process lasted from late 2021 until mid-2022. The U.S. National Aeronautics and Space Administration (NASA) led JWST's development in collaboration with the European Space Agency (ESA) and the Canadian Space Agency (CSA), beginning in the late 1990s. The NASA Goddard Space Flight Center (GSFC) in Maryland managed telescope development, the Space Telescope Science Institute in Baltimore on the Homewood Campus of Johns Hopkins University operates JWST, and the prime contractor was Northrop Grumman. The telescope is named after James E. Webb, who was…

Euclid is a wide-angle space telescope with a 600-megapixel camera to record visible light, a near-infrared spectrometer, and photometer, to determine the redshift of detected galaxies. It was developed by the European Space Agency (ESA) and the Euclid Consortium and was launched on 1 July 2023 from Cape Canaveral in Florida. The mission is named after the ancient Greek mathematician Euclid. After approximately one month, it reached its destination, a halo orbit around the Sun-Earth second Lagrange point L2, at an average distance of 1.5 million kilometres beyond Earth's orbit. There the telescope is to remain operational for at least six years. The objective of the Euclid mission is to bet…

James Webb Space Telescope: An astronomer explains the stunning, newly released first images

The Nancy Grace Roman Space Telescope is a NASA infrared space telescope that was launched on a trajectory toward a Sun–Earth L2 orbit on 30 August 2026. It is named after NASA's first chief of astronomy, Nancy Grace Roman. The telescope is based on an existing 2.4-meter (7.9-foot) primary mirror with a wide field of view that was donated by the National Reconnaissance Office and will carry two scientific instruments. The Wide-Field Instrument (WFI) is a 300.8-megapixel multi-band visible and near-infrared camera, providing image sharpness comparable to the Hubble Space Telescope over a 0.28-square-degree field of view, 100 times larger than imaging cameras on the Hubble. The Coronagraph In…

Red Spiral Galaxies at Cosmic Noon Unveiled in the First JWST Image. Abstract In the first image of the James Webb Space Telescope (JWST) of SMACS J0723.3-7327, one of the most outstanding features is the emergence of a large number of red spiral galaxies, because such red spiral galaxies are only a few percent in the number fraction among nearby spiral galaxies. While these apparently red galaxies were already detected with the Spitzer Space Telescope at ∼3–4 μ m, the revolutionized view from the JWST’s unprecedented spatial resolution has unveiled their hidden spiral morphology for the first time. Within the red spiral galaxies, we focus on the two reddest galaxies that are very faint in…

Creating the James Webb Space Telescope’s first color images. The first color images from the James Webb Space Telescope (JWST, Gardner et al. 2023) were designed with the understanding that a NASA/ESA/CSA flagship must explain its purpose and science to the tax- paying public, and that to earn the opportunity to explain and educate, we must first inspire. The feeling that many people have when seeing a well-composed color image of a deep space scene for the first time is visceral. It connects to a deeper part of the psyche than that of pure reason, like the effect of music or other visual arts. It is in eliciting this emotion that we have an opportunity to draw people in and educate; inevi…

Jane R. Rigby is an American astrophysicist who works at NASA's Goddard Space Flight Center (GSFC) as Senior Project Scientist of the James Webb Space Telescope (JWST). She has frequently made public appearances and is known for her association with the telescope. She has also worked to support inclusivity in science. In 2024, she was awarded the Presidential Medal of Freedom by President Joe Biden. Originally from Seaford, Delaware, Rigby received a bachelor's degree from Pennsylvania State University, followed by a master's degree and PhD from the University of Arizona. In 2010, Rigby joined GSFC as the deputy operations project scientist of the planned JWST, which had been facing cost an…

The Spitzer Space Telescope, formerly the Space Infrared Telescope Facility (SIRTF), was an infrared space telescope that was active between 2003 and 2020. Spitzer was the third space telescope dedicated to infrared astronomy, following IRAS (1983) and ISO (1995–1998). It was the first spacecraft to use an Earth-trailing orbit, later used by the Kepler planet-finder telescope. The planned mission period was to be 2.5 years with a pre-launch expectation that the mission could extend to five or slightly more years until the onboard liquid helium supply was exhausted. This occurred on 15 May 2009. Without liquid helium to cool the telescope to the very low temperatures needed to operate, most…

The Hubble Space Telescope (HST or Hubble) is a space telescope that was launched into low Earth orbit in 1990 and remains in operation. It was not the first space telescope, but it is one of the largest and most versatile, renowned as a vital research tool and as a public relations boon for astronomy. The Hubble Space Telescope is named after astronomer Edwin Hubble and is one of NASA's Great Observatories. The Space Telescope Science Institute (STScI) selects Hubble's targets and processes the resulting data, while the Goddard Space Flight Center (GSFC) controls the spacecraft. Hubble features a 2.4 m (7 ft 10 in) mirror, and its five main instruments observe in the ultraviolet, visible,…
