Assembling The Nancy Grace Roman Space Telescope | NASA

As NASA’s first Chief of Astronomy, the late Dr. Nancy Grace Roman paved the way for space telescopes and for women in the sciences. She is credited with making NASA’s Hubble Space Telescope a reality. In September 2024, the Nancy Grace Roman Space Telescope passed a key milestone and was approved for the next stage of construction. Work on the main systems that will make up the final spacecraft is finishing, and the team at NASA’s Goddard Space Flight Center is ready to begin integration, the process of connecting them together. 

This video celebrates the effort to reach the final stages of assembly.

Launching no later than May 2027, Roman is NASA’s next flagship mission.  An infrared survey telescope with the same resolution as Hubble, but 100 times the field of view, Roman is being built and tested at NASA’s Goddard Spaceflight Center in Greenbelt, Maryland. Partners from across the country are contributing to this effort.

Arrival of NASA's SpaceX Crew-9 Dragon Spacecraft | International Space Station

NASA Astronaut Don Pettit: "Here Be Dragons! The approach and docking sequence naturally draws our crew to a window; in this case, about five of us were crowded in Dragon Crew-8 to watch Dragon Crew-9 dock. With everyone bouncing around for a peek out the window, this photo was a quick handheld snap, complete with window reflections and streaky stars. This Dragon snorts fire! Welcome aboard Crew-9!"

NASA astronaut Nick Hague and Roscosmos cosmonaut Aleksandr Gorbunov of Russia arrived at the International Space Station on Sunday, Sept. 29, 2024. Their Crew-9 SpaceX Dragon Freedom spacecraft docked to the orbiting complex at 5:30 p.m. EDT while the station was 260 statute miles over Botswana.

Hague and Gorbunov were then welcomed by the space station’s Expedition 72 crew, including NASA astronauts Matthew Dominick, Michael Barratt, Jeanette Epps, Don Petitt, Butch Wilmore, and Suni Williams, as well as Roscosmos cosmonauts Alexander Grebenkin, Alexey Ovchinin, and Ivan Vagner of Russia.

An international partnership of space agencies provides and operates the elements of the International Space Station (ISS). The principals are the space agencies of the United States, Russia, Europe, Japan, and Canada. The ISS has been the most politically complex space exploration program ever undertaken.

Sun Releases Strongest Solar Flare (X9.0) of Solar Cycle 25 So Far | NASA SDO

NASA’s Solar Dynamics Observatory captured this image of a X9.0 solar flare—seen as the bright flash in the center—on Oct. 3, 2024. The image shows subsets of extreme ultraviolet light that highlight the extremely hot material in flares, colorized in red and gold. The Sun, shown in red and yellow, with several darker red and bright yellow spots. In the middle is a very bright white and yellow burst of energy with lines going in multiple directions, like a star.

NASA’s Solar Dynamics Observatory captured this image of an X9.0 solar flare—as seen in the bright flash in the center—on Oct. 03, 2024. The image shows a blend of 171 Angstrom, and 131 Angstrom light, subsets of extreme ultraviolet light.

NASA’s Solar Dynamics Observatory captured this image of an X9.0 solar flare—as seen in the bright flash in the center—on Oct. 03, 2024. The image shows 131 Angstrom extreme ultraviolet light. It highlights the extremely hot plasma of the flare.

The Sun emitted a strong solar flare in Active Region 3842, peaking at 8:18 a.m. ET on Oct. 3, 2024. The was the largest flare so far since the start of Solar Cycle 25 in 2019. NASA’s Solar Dynamics Observatory (SDO) watches the Sun constantly and captured imagery of the event.

Solar flares are powerful bursts of energy. Flares and solar eruptions can impact radio communications, electric power grids, navigation signals, and pose risks to spacecraft and astronauts.

This flare is classified as an X9.0 flare. X-class denotes the most intense flares, while the number provides more information about its strength.

Cosmoview Episodio 87: Entre los ardientes pétalos de la Nebulosa Roseta se encuentra NGC 2244, el joven cúmulo estelar que la alimenta. Sus estrellas iluminan la nebulosa con vibrantes tonos de rojo, oro y púrpura, mientras unas opacas torres de polvo se elevan desde las ondulantes nubes que rodean su núcleo excavado. NOIRLab publica esta imagen para celebrar su quinto aniversario, la cual fue tomada por la Cámara de Energía Oscura (DECam) de 570 megapíxeles que fabricó el Departamento de Energía de Estados Unidos y que se encuentra, montada en el Telescopio Víctor M.

The Rosette Nebula: Key Features | Victor Blanco Telescope

The Rosette Nebula: Key Features | Victor Blanco Telescope

This excerpt shows some of the interesting features of the Rosette Nebula. The dashed circle highlights the nebula's central star cluster, NGC 2244. The hazy smudge at the center of NGC 2244 is the young stellar object (YSO), Rosette HH1 (1). YSOs are stars in their early stage of evolution, before they become main-sequence stars, that often exhibit characteristics, such as jets, bipolar outflows, protoplanetary discs, and other indicators of a new star being born. Around the nebula’s excavated nucleus is a string of dark clouds dubbed ‘elephant trunks,’ so-named because of their trunk-like pillars (2, 4) One of these dark features is the Wrench Trunk (3). Unlike the prototypical Pillars of Creation trunks that stand like straight columns, the Wrench’s ‘handle’ has an unusual spiral shape. It  traces the magnetic field of the nebula. This image was captured with the Department of Energy-fabricated Dark Energy Camera (DECam), mounted on the U.S. National Science Foundation Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory, a Program of the NSF NOIRLab.

Gravitationally Lensed Supernova in Distant Galaxy Cluster | Webb Telescope

Gravitationally Lensed Supernova in Distant Galaxy Cluster | Webb Telescope

Measuring the Hubble constant, the rate at which the Universe is expanding, is an active area of research among astronomers around the world who analyze data from both ground- and space-based observatories. The NASA/European Space Agency/Canadian Space Agency James Webb Space Telescope has already contributed to this ongoing discussion. Earlier this year, astronomers used Webb data containing Cepheid variables and Type Ia supernovae, reliable distance markers to measure the Universe’s expansion rate, to confirm the NASA/ESA Hubble Space Telescope’s previous measurements.

Now, researchers are using an independent method of measurement to further improve the precision of the Hubble constant—gravitationally lensed supernovae. A supernova is the largest explosion that humans have ever seen. Each blast is the extremely bright, super-powerful explosion of a star. Researchers from institutions around the world are leading this effort after Webb’s discovery of three points of light in the direction of a distant and densely populated cluster of galaxies.

This is an image from Webb’s NIRCam (Near-Infrared Camera) of the galaxy cluster PLCK G165.7+67.0, also known as G165, on the left shows the magnifying effect a foreground cluster can have on the distant Universe beyond. The foreground cluster is 3.6 billion light-years away from Earth. The zoomed region on the right shows the supernova H0pe triply imaged (labeled with white dashed circles) due to gravitational lensing.

This field was selected for observation due to its high rate of star formation of more than 300 solar masses per year, an attribute that correlates with higher supernova rates. SN H0pe is one of the most distant Type Ia supernovae observed to date. The measured Hubble constant value matches other measurements in the local Universe, and is somewhat in tension with values obtained when the Universe was young. Future Webb observations in Cycle 3 will improve on the uncertainties.

In this image blue represents light at 0.9, 1.15, and 1.5 microns (F090W + F115W + F150W), green is 2.0 and 2.77 microns (F200W + F277W), and red is 3.56, 4.1, and 4.44 microns (F356W + F410M + F444W).

Note: This post highlights data from Webb science in progress, which has not yet been through the peer-review process.

Image Description: A two-panel image. In the left panel, dozens of small galaxies are scattered on the black background of space. Just to the left of the center, there is a long, red arc. At its left is a cluster of a few white galaxies that look like a glowing orb. To the right of the center, the red arc and glowing orb of galaxies at the left appear to be mirrored. The curved and distorted galaxy image on the right side is highlighted with a white box. Lines extend from the box’s corners to the right panel, which shows an enlarged view of the curved galaxy. Three faint points of light are circled.
