Galaxies may seem lonely, floating alone in the vast, inky blackness of the sparsely populated cosmos—but looks can be deceiving. The subject of this Picture of the Week, NGC 1706, is a good example of this. NGC 1706 is a spiral galaxy, about 230 million light-years away, in the constellation of Dorado (The Swordfish).

NGC 1706 is known to belong to something known as a galaxy group, which is just as the name suggests—a group of up to 50 galaxies which are gravitationally bound and hence relatively close to each other. Around half of the galaxies we know of in the Universe belong to some kind of group, making them incredibly common cosmic structures. Our home galaxy, the Milky Way, belongs to the Local Group, which also contains the Andromeda Galaxy, the Large and Small Magellanic Clouds, and the Triangulum Galaxy.

Groups are the smallest of galactic gatherings; others are clusters, which can comprise hundreds of thousands of galaxies bound loosely together by gravity, and subsequent superclusters, which bring together numerous clusters into a single entity.

This strikingly simple and serene view of NGC 1404—a giant elliptical galaxy located 62 million light-years away in the constellation of Fornax (The Furnace)—hides the galaxy’s cruel reality.

NGC 1404 is one of the galaxies comprising the massive Fornax Cluster—and it is slowly falling inwards towards the cluster’s core. As it moves towards the cluster’s large centermost galaxy, NGC 1399, the galaxy’s reserves of hot gas are being forcibly ripped and stripped away, leaving an elongated tell-tale trail of gas in its wake. While not visible in this image, this gas stream can be seen clearly in X-ray images of the galaxy; in time, NGC 1404 will lose most of its hot gas, and therefore its ability to form new stars.


The European Southern Observatory's Very Large Telescope (VLT) captured this image of NGC 1404 with its FORS instrument. The bright foreground star to the lower left of the frame is named HD 22862.

NASA's Space to Ground: Space Jam | Week of October 25, 2019

NASA's Space to Ground: Space Jam

Week of October 25, 2019

NASA's Space to Ground is your weekly update on what's happening aboard the International Space Station.

The six residents living aboard the International Space Station are busy today ensuring advanced microgravity research continues to provide benefits for citizens on Earth and in space. The Expedition 61 crew is also brushing up on repair techniques for a cosmic particle detector attached to the outside of the orbiting lab.

NASA astronauts Jessica Meir and Christina Koch juggled an array of life science activities throughout Thursday. Meir cared for plants for a new field of botany research exploring how to provide fresh food for long-term space crews. Meir later swapped out a failed computer hard drive that supports combustion experiments. Koch organized biology hardware for a study seeking therapies for aging-related conditions. Koch then serviced microbial DNA samples to understand how microorganisms adapt to weightlessness.

The Alpha Magnetic Spectrometer (AMS-02) is due for an upgraded thermal control system after being installed on the outpost’s Starboard-3 truss structure in 2011. NASA is planning a series of spacewalks to restore the AMS-02 to full service. Commander Luca Parmitano of ESA (European Space Agency) and NASA Flight Engineer Andrew Morgan are reviewing the tools and techniques necessary to complete the AMS repair job.

Over in the station’s Russian segment, composed of five modules, a pair of cosmonauts focused on hardware and systems maintenance. Alexander Skvortsov inspected lab windows and checked batteries. Fellow cosmonaut Oleg Skripochka worked on air conditioning and plumbing tasks inside the orbital lab. The duo also explored how to improve accuracy when detecting and photographing Earth landmarks.

NASA Astronauts Christina Koch & Jessica Meir Reflect on First All-Woman Spacewalk

NASA Astronauts Christina Koch & Jessica Meir Reflect on First All-Woman Spacewalk

NASA astronauts Christina Koch and Jessica Meir reflect on the historic spacewalk they performed on Oct. 18—the first ever to be conducted by two women. They spent a total of 7 hours and 17 minutes in the vacuum of space. It was Koch’s fourth spacewalk and Meir’s first.

It is the first spaceflight for both women, who were selected in the 2013 astronaut class that had equal numbers of women and men. Koch arrived to the orbiting laboratory in March 2019 and will remain in space for an extended duration mission of 11 months to provide researchers the opportunity to observe effects of long-duration spaceflight on a woman to prepare for human missions to the Moon and Mars.

Meir became the 15th woman to spacewalk, and the 14th U.S. woman. It was the 43rd spacewalk to include a woman. Women have been performing spacewalks since 1984.

A Fleeting Moment in Time: A Dying Star | ESO

A Fleeting Moment in Time: A Dying Star | ESO

The faint, ephemeral glow emanating from the planetary nebula ESO 577-24 persists for only a short time—around 10,000 years, a blink of an eye in astronomical terms. The European Southern Observatory's Very Large Telescope captured this shell of glowing ionized gas—the last breath of the dying star whose simmering remains are visible at the heart of this image. As the gaseous shell of this planetary nebula expands and grows dimmer, it will slowly disappear from sight.


This stunning planetary nebula was imaged by one of the VLT’s most versatile instruments, FORS2. The instrument captured the bright, central star, Abell 36, as well as the surrounding planetary nebula. The red and blue portions of this image correspond to optical emission at red and blue wavelengths, respectively.

An object much closer to home is also visible in this image—an asteroid wandering across the field of view has left a faint track below and to the left of the central star. And in the far distance behind the nebula a glittering host of background galaxies can be seen.

Starshine in Canis Major | ESO

Starshine in Canis Major | ESO

Distance: 5000 light years

It is impossible to miss the star in this European Southern Observatory (ESO) Picture of the Week—beaming proudly from the center of the frame is the massive multiple star system Tau Canis Majoris, the brightest member of the Tau Canis Majoris Cluster (NGC 2362) in the eponymous constellation of Canis Major (The Great Dog). Tau Canis Majoris aside, the cluster is populated by many young and less attention-seeking stars that are only four or five million years old, all just beginning their cosmic lifetimes.

The Tau Canis Majoris Cluster is an open cluster—a group of stars born from the same molecular cloud. This means that all of the cluster’s inhabitants share a common chemical composition and are loosely bound together by gravity. Having been born together, they make an ideal stellar laboratory to test theories of stellar evolution, the chain of events that leads from a star’s birth in a cool, dense cloud of gas through to its eventual death.

Though the stars in this image were all created at the same time, their various different masses mean they will lead very different lives. As Tau Canis Majoris is one of the most massive and short-lived types of star, it will burn through its nuclear fuel long before its smaller companions, which will keep on shining for billions of years.

This image was created as part of the ESO Cosmic Gems program, an outreach initiative to produce images of interesting, intriguing or visually attractive objects using ESO telescopes, for the purposes of education and public outreach. The program makes use of telescope time that cannot be used for science observations. All data collected may also be suitable for scientific purposes, and are made available to astronomers through ESO’s science archive.

Towers under the Milky Way | ESO

Towers under the Milky Way | ESO

This picture shows in the foreground some of the towers supporting the telescopes that compose BlackGEM. In the background, the magnificent southern Milky Way shines in the sky.

BlackGEM is a wide-field array of optical telescopes located at the European Southern Observatory’s La Silla Observatory in Chile’s Atacama desert.

BlackGEM’s scientific goals are to detect and characterize optical counterparts to gravitational wave detections. To enable this, it will conduct an all-sky survey of the southern sky, perform a bi-weekly scan of the southern sky, and characterize intra-night transients, new stars that appear or disappear within a single night.

Events that produce detectable gravitational waves are expected to occur within approximately 650 million light-years of Earth. Many will therefore be located in or near resolved galaxies and will be faint. It is essential for BlackGEM to have high spatial resolution in order to resolve and accurately locate these sources against the background of the night-sky, making La Silla—with its excellent weather and thin atmosphere—an ideal observing site.

Oct. 18, 2019: The International Space Station Expedition 61 crew pauses for a photo as NASA Astronauts Jessica Meir and Christina Koch prepare to exit the International Space Station to begin the first all female spacewalk in history on Oct. 18, 2019.

The astronauts replaced a faulty battery charge discharge unit (BCDU) that failed to activate following the Oct. 11 installation of new lithium ion batteries on the space station's exterior structure. The BCDUs regulate the amount of charge put into the batteries that collect energy from the station's solar arrays to power station systems during periods when the station orbits during nighttime passes around Earth. Though the BCDU failure has not impacted station operations or crew safety, it does prevent the new batteries from providing increased station power.

Commander Luca Parmitano of the European Space Agency (ESA) and NASA Flight Engineer Andrew Morgan assisted the spacewalkers. Parmitano operated the Canadarm2 robotics arm and Morgan provided airlock and spacesuit support.

It was the first spacewalk for Meir and the fourth for Koch, who now has spent a total of 27 hours and 48 minutes spacewalking. It is the first spaceflight for both women, who were selected in the 2013 astronaut class that had equal numbers of women and men. Koch arrived to the orbiting laboratory in March 2019 and will remain in space for an extended duration mission of 11 months to provide researchers the opportunity to observe effects of long-duration spaceflight on a woman to prepare for human missions to the Moon and Mars.
