Three Galaxies in Draco

Three Galaxies in Draco

This tantalizing trio of galaxies sometimes called the Draco Group, is located in the northern constellation of (you guessed it) Draco, the Dragon. From left to right are face-on spiral NGC 5985, elliptical galaxy NGC 5982, and edge-on spiral NGC 5981, all found within this single telescopic field of view that spans a little more than the width of the full moon. While the group is far too small to be a galaxy cluster, and has not been cataloged as a compact galaxy group, the three galaxies all do lie roughly 100 million light-years from planet Earth. Not as well known as other tight groupings of galaxies, the contrast in visual appearance still makes this triplet an attractive subject for astroimagers. 

On close examination with spectrographs, the bright core of striking spiral NGC 5985 shows prominent emission in specific wavelengths of light, prompting astronomers to classify it as a Seyfert, a type of active galaxy. This impressively deep exposure hints at a faint dim halo along with sharp-edged shells surrounding elliptical NGC 5982, evidence of past galactic mergers. It also reveals many even more distant background galaxies.

Lift-off of Europe's Euclid Space Telescope to Explore The Dark Universe | SpaceX

Lift-off of Europe's Euclid Space Telescope to Explore The Dark Universe | SpaceX

The European Space Agency’s latest astrophysics mission, Euclid, lifted off on a SpaceX Falcon 9 from Cape Canaveral in Florida, USA, at 11:12 am ET on July 1, 2023. Euclid has now started its month-long journey to Sun-Earth Lagrange point L2, located 1.5 million kilometers from Earth, in the opposite direction from the Sun. The space telescope will survey one third of the sky with unprecedented accuracy and sensitivity. By observing billions of galaxies out to 10 billion light-years, it will create the most extensive 3D-map of the Universe, with the third dimension representing time.

The European Space Agency’s Euclid Mission is designed to explore the composition and evolution of the dark Universe. Euclid will chart how the Universe has expanded and how large-scale structure is distributed across space and time, revealing more about the role of gravity and the nature of dark energy and dark matter.

Four weeks after launch, Euclid will enter its orbit around L2. Once in orbit, mission controllers will start the activities to verify all functions of the spacecraft, check out the telescope and finally turn the instruments on.

Following this, scientists and engineers will be engaged in an intense two-month phase of testing and calibrating Euclid’s scientific instruments, and preparing for routine observations. The telescope begins its early phase of the survey of the Universe three months after launch.

The SpaceX Falcon 9 rocket carrying the European Space Agency’s Euclid mission at its launch pad in Cape Canaveral, Florida, where it was successfully launched at 11:12 am ET on July 1, 2023.

The European Space Agency’s Euclid mission is designed to explore the composition and evolution of the dark Universe. Euclid will chart how the Universe has expanded and how large-scale structure is distributed across space and time, revealing more about the role of gravity and the nature of dark energy and dark matter.  

Four weeks after launch, Euclid will enter in orbit around Sun-Earth Lagrange point L2. Once in orbit, mission controllers will start the activities to verify all functions of the spacecraft, check out the telescope and finally turn the instruments on.  

The goal of the European Space Agency’s Euclid mission is to bring the dark side of the Universe to light. Based on the way galaxies rotate and orbit one another, and the way in which the Universe is expanding, astronomers believe that two unseen entities dominate the composition of our cosmos. They call these mysterious components dark matter and dark energy, yet to date we have not been able to detect either of them directly, only inferring their presence from the effects they have on the Universe at large.

The European Space Agency’s Euclid mission will create a 3D-map of the Universe, with the third dimension representing time itself. The further away a galaxy is located, the longer its light has taken to reach us and so the earlier in cosmic history we will see it. By observing billions of galaxies out to a distance of 10 billion light-years, scientists will be able to chart the position and velocity of galaxies over immense distances and through most of cosmic history, and trace the way the Universe has expanded during that time. Euclid’s extraordinary optics will also reveal subtle distortions in the appearance of galaxies.

From this wealth of new data, astronomers will be able to infer the properties of dark energy and dark matter more precisely than ever before. This will help theorists pin down the nature of these mysterious components and develop a refined understanding of how gravity behaves at the largest distances.

Saturn’s Rings & Moons Dione, Enceladus & Tethys | James Webb Space Telescope

Saturn’s Rings & Moons Dione, Enceladus & Tethys | James Webb Space Telescope

Webb took its first near-infrared look at Saturn on June 25, 2023. The planet appears extremely dark at this wavelength, as methane gas in its atmosphere absorbs sunlight, but its rings stay bright!

Description: The background is mostly dark. At the center is a dark orange-brownish circle, surrounded by several blazing bright, thick, horizontal whiteish rings. This is Saturn and its rings. There are three tiny dots in the image—one to the upper left of the planet, one to the direct left of the planet, and the lower left of the planet. They are labeled Dione, Enceladus, and Tethy, respectively. There is a slightly darker tint at the northern and southern poles of the planet. The rings surrounding Saturn are mostly broad, with a few singular narrow gaps between the broader rings. At the right side of the planet, labels are applied to the rings. The innermost, thicker ring is labeled “C ring.” Next to that, a brighter, wider ring is labeled “B ring.” Traveling farther outward, a small dark gap is labeled “Cassini division” before another thicker ring labeled “A ring.” Within the “A ring,” a narrow faint band is labeled “Encke gap.” The outermost, faintest, thinnest ring is labeled “F ring.

This image was taken as part of a Webb science program designed to test the telescope’s capacity to detect faint moons around the planet and study its bright rings. Take a closer look here to find details within the planet's ring system, as well as the moons Dione, Enceladus, and Tethys. Saturn’s rings are made up of an array of rocky and icy fragments—the particles range in size from smaller than a grain of sand to a few as large as mountains on Earth.

Extreme Heat and Severe Weather Plague Parts of North America | NOAA

Extreme Heat and Severe Weather Plague Parts of North America | NOAA

A dangerous heat wave that has been affecting more than 50 million people across the southern U.S. and Mexico expanded its reach this week, bringing more dangerous triple-digit temperatures to the region. At the same time, many others were affected by numerous thunderstorms and some tornadoes within the Plains and central U.S. NOAA satellites and forecasting models have been monitoring the record-breaking temperatures, which are being brought on by what is called a “heat dome,” in addition to the severe weather.  

A heat dome occurs when a persistent region of high-pressure traps heat over a particular area, and it can linger for days to weeks. Heat domes are typically linked to the behavior of the jet stream, which is a band of fast-moving winds high in the atmosphere that move in meandering wavelike patterns. When the jet stream meanders north, it moves slower and can sink, which lowers humidity. This allows the sun to create progressively hotter conditions on the ground. Air descending down mountains can also contribute to heat domes, as it warms even more.

‘Asteroid City’ Cast Asks NASA About OSIRIS-REx Asteroid Mission

‘Asteroid City’ Cast Asks NASA About OSIRIS-REx Asteroid Mission

In September 2023, scientists with NASA’s OSIRIS-REx mission will gather in the Utah desert for the arrival of the largest asteroid sample ever received on Earth. “Asteroid City” actors, including Scarlett Johansson, Jason Schwartzman, Maya Hawke, Rupert Friend and Jeffrey Wright, join NASA OSIRIS-REx sample expert Dr. Danny Glavin to discuss how studying the asteroid sample will give scientists insight into how the early solar system formed and how life began on Earth.

After a seven-year round trip journey that included mapping Bennu’s surface (a near-Earth asteroid that is no threat to our planet), identifying minerals and chemicals, and collecting a sample from the surface, OSIRIS-REx is on its way back to Earth with more than eight ounces of material.

NASA's Space to Ground: Making a Splash | Week of June 30, 2023

NASA's Space to Ground: Making a Splash | Week of June 30, 2023

    

NASA's Space to Ground is your weekly update on what's happening aboard the International Space Station. A SpaceX Dragon cargo spacecraft splashed down at 10:30 a.m. EDT Friday, June 30, 2023, off the coast of Jacksonville, Florida, marking the return of the company’s 28th contracted cargo resupply mission to the International Space Station for NASA. The spacecraft carried approximately 3,600 pounds of valuable scientific experiments and other cargo back to Earth.

Scientific hardware and samples returning on the mission include the GRIP—Dexterous Manipulation in Microgravity chair used in the European Space Agency (ESA)-sponsored neurology experiments GRIP and GRASP (Gravitational References for Sensimotor Performance: Reaching and Grasping). GRIP studies how microgravity affects the manipulation of objects, while GRASP provides further insight into how the central nervous system adapts to the microgravity environment. The experiments have been on the space station almost six years, and the final in-orbit tests were completed in early 2023.

Samples from BioNutrients-2, Monoclonal Antibodies, and Myotones investigations also are returning to Earth for scientific analysis.

Orbits of Potentially Hazardous Asteroids | NASA/JPL

Orbits of Potentially Hazardous Asteroids | NASA/JPL

Are asteroids dangerous? Some are, but the likelihood of a dangerous asteroid striking the Earth during any given year is low. Some past mass extinction events have been linked to asteroid impacts. However, humanity has made it a priority to find and catalog those asteroids that may one day affect life on Earth. Pictured here are the orbits of the over 1,000 known Potentially Hazardous Asteroids (PHAs). These documented tumbling boulders of rock and ice are over 140 meters across and will pass within 7.5 million kilometers of Earth—about 20 times the distance to the Moon. Although none of them will strike the Earth in the next 100 years—not all PHAs have been discovered, and past 100 years, many orbits become hard to predict. Were an asteroid of this size to impact the Earth, it could raise dangerous tsunamis, for example. To investigate Earth-saving strategies, NASA successfully tested the Double Asteroid Redirection Test (DART) mission last year. Of course, rocks and ice bits of much smaller size strike the Earth every day, usually pose no danger, and sometimes create memorable fireball and meteor displays.
