Planet Mars: A New Impact Event | NASA's Mars Reconnaissance Orbiter

Planet Mars: A New Impact Event | NASA's Mars Reconnaissance Orbiter

This impact disturbed dust over an area more than two kilometers wide, large enough to be visible in Mars Color Imager (MARCI) daily global images. The largest new crater is about 35 meters in diameter, making it the about the 16th largest new crater found on Mars. By “new crater” we mean that its formation is documented by before and after images, usually acquired by MRO’s Context Camera. There are many other new craters formed up to a kilometer away from the biggest crater. These appear unusual for secondary craters produced by the main 35-meter crater, and are probably more like primary craters resulting from fragmentation of the bolide high in the Martian atmosphere.

Touring Tempestuous Young Stars in The Orion Nebula | Hubble

Touring Tempestuous Young Stars in The Orion Nebula | Hubble

The bright variable star V 372 Orionis takes center stage in this image from the NASA/European Space Agency Hubble Space Telescope, which has also captured a smaller companion star in the upper left of this image. Both stars lie in the Orion Nebula, a colossal region of star formation roughly 1,450 light years from Earth.

Image Description: Two very bright stars with cross-shaped diffraction spikes are prominent: the larger is slightly lower-right of center, the smaller lies towards the upper-left corner. Small red stars with short diffraction spikes are scattered around them. The background is covered nearly completely by gas: smoky, bright blue gas around the larger star in the center and lower-right, and wispier red gas elsewhere.

V 372 Orionis is a particular type of variable star known as an Orion Variable. These young stars experience some tempestuous moods and growing pains, which are visible to astronomers as irregular variations in luminosity. Orion Variables are often associated with diffuse nebulae, and V 372 Orionis is no exception; the patchy gas and dust of the Orion Nebula pervade this scene.

This image overlays data from two of Hubble’s instruments. Data from the Advanced Camera for Surveys and Wide Field Camera 3 at infrared and visible wavelengths were layered to reveal rich details of this corner of the Orion Nebula. Hubble also left its own subtle signature on this astronomical portrait in the form of the diffraction spikes surrounding the bright stars. These prominent artefacts are created by starlight interacting with Hubble’s inner workings, and as a result they reveal hints of Hubble’s structure. The four spikes surrounding the stars in this image are created by four vanes inside Hubble supporting the telescope’s secondary mirror. The diffraction spikes of the NASA/European Space Agency/Canadian Space Agency James Webb Space Telescope, on the other hand, are six-pointed as a result of Webb’s hexagonal mirror segments and 3-legged support structure for the secondary mirror.

Has COVID Affected Climate Change? We Asked a NASA Scientist

Has COVID Affected Climate Change? We Asked a NASA Scientist

Greenhouse gas emissions decreased a little during the first year of COVID-19, but not enough to make a lasting impact.

Less travel and cars on the road meant improved air quality. However, greenhouse gases that cause climate change only decreased a little because we were still heating and cooling our homes, so these gases continued to build up in our atmosphere. NASA climate change scientist Lesley Ott tells us more about what scientists discovered.

Rocket Lab Launches First Electron Rocket from Virginia | NASA Wallops

Rocket Lab Launches First Electron Rocket from Virginia | NASA Wallops

Rocket Lab performed its long-awaited first Electron launch from Virginia Jan. 24, 2023, placing three HawkEye 360 satellites into orbit. The Electron rocket lifted off from Launch Complex 2 at the Mid-Atlantic Regional Spaceport on Wallops Island, Virginia, at 6 p.m. Eastern. Electron carried three satellites for HawkEye 360, the Herndon, Virginia-based company that offers radio-frequency (RF) intelligence services. The “Cluster 6” satellites, deployed into a 550-kilometer orbit at an inclination of 40.5 degrees, will join the company’s constellation to locate and monitor terrestrial RF sources. 

The mission, called “Virginia Is For Launch Lovers” by Rocket Lab, was the company’s first launch from LC-2. The company’s previous 32 Electron launches took place from its Launch Complex 1 in New Zealand. Rocket Lab had been working for years to set a U.S. launch site to support government and other customers who wanted to launch domestically. The launch is the first of the year for Rocket Lab, which said in a November earnings call it was planning approximately 14 Electron launches in 2023 after conducting nine in 2022. The company projected that four to six of those launches would take place from Wallops, including two launches in the spring to deploy NASA’s four Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats (TROPICS) cubesats under a task order NASA announced in November.

Print-Ready 2023 Calendar (Adobe PDF, 586 MB) *Large File Size*: 

https://esahubble.org/media/archives/announcements/pdf/calendar_hubble_2023_v05_print.pdf

The 2023 calendar features a selection of images from Press Releases (from Hubble and Webb), Hubble Pictures of the Week and Webb Pictures of the Month published throughout 2022. These include imagery of planets, star clusters, galaxies, and more. It can now be accessed electronically for anyone to print, share and enjoy.

The images featured in the calendar are as follows:

Cover: This landscape of mountains and valleys speckled with glittering stars is actually the edge of a nearby, young, star-forming region called NGC 3324 in the Carina Nebula. Captured in infrared light by the James Webb Space Telescope, this image reveals for the first time previously invisible regions of star birth.

January: The protostar L1527, shown in this image from the James Webb Space Telescope, is embedded within a cloud of material that is feeding its growth. Material ejected from the star has cleared out cavities above and below it, whose boundaries glow orange and blue in this infrared view.

February: The image on the left is the first deep-field image from the James Webb Space Telescope, showcasing thousands of galaxies of the galaxy cluster SMACS 0723 in the near-infrared. The image on the right from the Hubble Space Telescope features the galaxy cluster Abell 611, located roughly 3.2 billion light-years from Earth.

March: In this mosaic image stretching 340 light-years across, the James Webb Space Telescope showcases the Tarantula Nebula star-forming region in infrared light, including tens of thousands of previously unseen young stars that are obscured by cosmic dust in visible-light images.

April: This month features four galaxy mergers. The objects are IC 1623 (top left, as seen by Webb), Arp 248 (bottom left, as seen by Hubble), Arp 282 (top right, as seen by Hubble), and IC 2431 (bottom right, as seen by Hubble).

May: Two views from the James Webb Space Telescope reveal the planetary nebula NGC 3132, also known as the Southern Ring. The left image is a sharp near-infrared view of the nebula, while the view on the right is in mid-infrared wavelengths, and captures the dust shrouding one of the white dwarf stars at the nebula’s centre.

June: Jupiter, the largest planet in our Solar System, is featured here in near-infrared wavelengths as seen by the James Webb Space Telescope. Different colours mark the light from the planet’s aurorae, and the clouds and hazes at different depths in the atmosphere. The Great Red Spot shines brightly with reflected near-infrared light from the Sun.

July: This montage displays four globular star clusters as seen by the Hubble Space Telescope. Shown here are Liller 1 (top left), Terzan 9 (bottom left), Terzan 4 (top right) and NGC 6569 (bottom right). Each is filled with both redder, older stars and bluer, younger ones.

August: These images show unusual, densely packed groupings of entire galaxies. The left image, in visible light from the Hubble Space Telescope, is of the soon-to-merge galaxies of HCG 40. The right image, taken by the James Webb Space Telescope in infrared light, is of the interacting galaxies of HCG 92 — also known as Stephan’s Quintet.

September: This celestial cloudscape from the Hubble Space Telescope captures the colourful region surrounding the Herbig-Haro object HH 505. The Orion Nebula is awash in intense ultraviolet radiation from bright young stars. Outflows from such stars collide with gas and dust, creating the shockwaves known as Herbig-Haro objects that are brightly visible to Hubble.

October: This montage features three views of M74, also known as the Phantom Galaxy. The left section of this image is a visible-light image from the Hubble Space Telescope, while the right section, in mid-infrared wavelengths, comes from the James Webb Space Telescope. In the centre, data from both telescopes are combined for a truly unique view into the heart of the object.

November: Two views of the famous Pillars of Creation, part of the Eagle Nebula, are revealed here by the James Webb Space Telescope. The left, mid-infrared, image details the spread of interstellar dust. On the right, the near-infrared image highlights bright, newly-formed stars.

December: NGC 7038 is displayed in glorious detail here by the Hubble Space Telescope. The image is remarkably detailed, combining over 15 hours of observations to expose distant stars and galaxies in the background. The spiral galaxy filling the frame here contains celestial objects that can be used to measure distances on cosmic scales.

Star Cluster NGC 1850 | Hubble

Star Cluster NGC 1850 | Hubble

Star cluster NGC 1850 is approximately 63,000 times the mass of the Sun, and its core is roughly 20 light-years in diameter. This 100 million-year-old globular cluster is located in the Large Magellanic Cloud, a satellite galaxy of the Milky Way and a birthplace for billions of stars. The cluster is approximately 160,000 light-years away in the constellation Dorado. Typical of globular clusters, it is a spherical collection of densely packed stars held together by mutual gravitational attraction. Unlike most globular clusters, however, the stars of NGC 1850 are relatively young. Globular clusters with young stars such as NGC 1850 are not present in our own Milky Way galaxy.

Astrophysicists theorize that when the first generation of stars in NGC 1850 was born, the stars ejected matter like dust and gas into the surrounding cosmos. The density of the newly formed star cluster was so high that this ejected matter could not escape the cluster’s gravitational pull, causing it to stay nearby. The intense gravity of the cluster also pulled in hydrogen and helium gas from its surroundings. These two sources of gas combined to form a second generation of stars, increasing the density and size of this globular cluster.

In 2021, scientists detected the presence of a black hole in NGC 1850. They have also detected many brighter blue stars (seen on the right of the second image) that burn hotter and die younger than red stars. Also present are around 200 red giants, stars that have run out of hydrogen in their centers and are fusing hydrogen further from their core, causing the outer layers to expand, cool, and glow red (seen throughout the second image). Surrounding the cluster is a pattern of nebulosity, diffuse dust and gas theorized to come from supernova blasts (the blue veil-like structures on the first image and the red ones on the second image).

Pan of Molecular Cloud Chameleon I | James Webb Space Telescope

Pan of Molecular Cloud Chameleon I | James Webb Space Telescope

This video features a new image from the NASA/European Space Agency/Canadian Space Agency James Webb Space Telescope’s Near-InfraRed Camera (NIRCam) features the central region of the Chameleon I dark molecular cloud, which resides 630 light years away. The cold, wispy cloud material (blue, center) is illuminated in the infrared by the glow of the young, outflowing protostar Ced 110 IRS 4 (orange, upper left). The light from numerous background stars, seen as orange dots behind the cloud, can be used to detect ices in the cloud, which absorb the starlight passing through them.

A molecular cloud is a vast interstellar cloud of gas and dust in which molecules can form, such as hydrogen and carbon monoxide. Cold, dense clumps in molecular clouds with higher densities than their surroundings can be the sites of star formation if these clumps collapse to form protostars.

An international team of astronomers has reported the discovery of diverse ices in the darkest, coldest regions of a molecular cloud measured to date by studying this region. This result allows astronomers to examine the simple icy molecules that will be incorporated into future exoplanets, while opening a new window on the origin of more complex molecules that are the first step in the creation of the building blocks of life.

This research forms part of the Ice Age project, one of Webb's 13 Early Release Science programs, which has studied a dust ridge in the centre of the Chameleon I molecular cloud.

In its top half it is textured like smoke and has wispy gaps, while at the bottom and at the sides it fades gradually out of view. On the left are several orange stars: three each with six large spikes, and one behind the cloud which colors it pale blue and orange. Many tiny stars are visible, and the background is black.

A molecular cloud is a vast interstellar cloud of gas and dust in which molecules can form, such as hydrogen and carbon monoxide. Cold, dense clumps in molecular clouds with higher densities than their surroundings can be the sites of star formation if these clumps collapse to form protostars.

An international team of astronomers has reported the discovery of diverse ices in the darkest, coldest regions of a molecular cloud measured to date by studying this region. This result allows astronomers to examine the simple icy molecules that will be incorporated into future exoplanets, while opening a new window on the origin of more complex molecules that are the first step in the creation of the building blocks of life.
