Hubble’s Inside The Image: M87 Jet | NASA Goddard

The Hubble Space Telescope has taken over 1.5 million observations over the years. One of them is the incredible image of galaxy M87 and its giant jet. M87, a massive elliptical galaxy in the Virgo Cluster, is famous for its prominent jet of high-energy particles and radiation that extends for thousands of light-years from its central supermassive black hole. In this video, Dr. Padi Boyd explains this breathtaking image and how important Hubble is to exploring the mysteries of the universe.

The Orion Nebula [AKA "The Great Turkey Nebula"] | Hubble

The Orion Nebula [AKA "The Great Turkey Nebula"] | Hubble

Happy Thanksgiving, All! | Note: "AKA" is an abbreviation for "also known as".

"It is not Thanksgiving without turkey!" 

Although there is no official deep-sky object bearing the "Great Turkey Nebula" name, observers like to imagine the famous Orion Nebula (M42) as the "Great Turkey Nebula".

This dramatic image offers a peek inside a cavern of roiling dust and gas where thousands of stars are forming. The image, taken by the Advanced Camera for Surveys (ACS) aboard NASA/European Space Agency Hubble Space Telescope, represents the sharpest view ever taken of this region, called the Orion Nebula. More than 3,000 stars of various sizes appear in this image. Some of them have never been seen in visible light. These stars reside in a dramatic dust-and-gas landscape of plateaus, mountains, and valleys that are reminiscent of the Grand Canyon.

The Orion Nebula is a picture book of star formation, from the massive, young stars that are shaping the nebula to the pillars of dense gas that may be the homes of budding stars. The bright central region is the home of the four heftiest stars in the nebula. The stars are called the Trapezium because they are arranged in a trapezoid pattern. Ultraviolet light unleashed by these stars is carving a cavity in the nebula and disrupting the growth of hundreds of smaller stars. Located near the Trapezium stars are stars still young enough to have disks of material encircling them. These disks are called protoplanetary disks or "proplyds" and are too small to see clearly in this image. The disks are the building blocks of solar systems.

The bright glow at upper left is from M43, a small region being shaped by a massive, young star's ultraviolet light. Astronomers call the region a miniature Orion Nebula because only one star is sculpting the landscape. The Orion Nebula has four such stars. Next to M43 are dense, dark pillars of dust and gas that point toward the Trapezium. These pillars are resisting erosion from the Trapezium's intense ultraviolet light. The glowing region on the right reveals arcs and bubbles formed when stellar winds—streams of charged particles ejected from the Trapezium stars—collide with material.

The faint red stars near the bottom are the myriad brown dwarfs that Hubble spied for the first time in the nebula in visible light. Sometimes called "failed stars," brown dwarfs are cool objects that are too small to be ordinary stars because they cannot sustain nuclear fusion in their cores the way our Sun does. The dark red column, below, left, shows an illuminated edge of the cavity wall.

The Orion Nebula is about 1,600 light-years away, the nearest star-forming region to Earth. Astronomers used 520 Hubble images, taken in five colors, to make this picture. They also added ground-based photos to fill out the nebula. The ACS mosaic covers approximately the apparent angular size of the full moon.

The Orion observations were taken between 2004 and 2005.

"It is not Thanksgiving without turkey!" 
Although there is no official deep-sky object bearing the "Great Turkey Nebula" name, observers like to imagine the famous Orion Nebula (M42) as the "Great Turkey Nebula".

M42 is the most famous of all nebulae. Galileo missed this object entirely, but William Herschel had the eerie foresight to call it "the chaotic material of future suns." It is a star forming region all right, one of the closest at a mere 1,600 lightyears. There is enough material here for 10,000 stars like the sun. The bright central region is an irregular cloud about six lightyears across. Four stars in the center (the Trapezium) have recently formed and provide the energy to light up the nebula. You can find this object in the Sword of Orion, just under the three famous belt stars. Binoculars are enough.

This image was taken as part of Advanced Observing Program (AOP) program at Kitt Peak Visitor Center during 2014.

"The Great Turkey Nebula"

"The Great Turkey Nebula"

Happy Thanksgiving, Everyone! 

"It is not Thanksgiving without turkey!" 

Although there is no official deep-sky object bearing this bird’s name, observers like to imagine the famous Orion Nebula (M42) as the Great Turkey Nebula. Surprisingly reminiscent of The Great Nebula in Orion, The Great Turkey Nebula spans this creative field of view. Of course, if it were the Orion Nebula it would be our closest large stellar nursery, found at the edge of a large molecular cloud a mere 1,500 light-years away. 

The Orion Nebula, also known as M42, is visible to the eye as the middle "star" in the sword of Orion the Hunter, a constellation in planet Earth's skies. Stellar winds from clusters of newborn stars scattered throughout the Orion Nebula sculpt its ridges and cavities seen in familiar in telescopic images. Much larger than any bird you might be cooking, this Great Turkey Nebula was imagined to be similar in size to the Orion Nebula, about 13 light-years across. 

The Orion Nebula can be easily seen with binoculars or any telescope as a gauzy, bright glow surrounding several tightly packed bright stars—these are the Trapezium Cluster, birthed from the clouds of gas and dust that make up the nebula. These massive suns are now starting to sculpt the clouds with the intense winds they blast out.

Take some time to study the nebula and its shape. Does it look like a Turkey to you? The “head” is a hooked cloud along the northern edge, with the large, round body and fanned-out tail extending to the south. If you cannot see enough detail at the eyepiece, consider taking a photograph. This will gather more light than your eye is capable of bringing in to better highlight the clouds’ shape more sharply. If you do not see the Great Turkey Nebula, M42 is still one of the very best deep-sky sights you can catch to top off an excellent evening of family and feasting.

Planet Venus "Meets" Earth Meteor over Colorado

Planet Venus "Meets" Earth Meteor over Colorado

"It came from outer space."

Meteors can be colorful. While the human eye usually cannot discern many colors, cameras often can. Colors in meteors usually originate from ionized chemical elements released as the meteor disintegrates. Blue-green colors typically originate from magnesium, calcium radiates violet, and nickel glows green. Red, however, typically originates from energized nitrogen and oxygen in the Earth's atmosphere. This bright meteoric fireball was gone in a flash—less than a second—but it left a wind-blown ionization trail that remained visible.

NASA's Ingenuity Mars Helicopter: Two Views of a High-Altitude Flight | JPL

NASA's Ingenuity Mars Helicopter: Two Views of a High-Altitude Flight | JPL 

As NASA’s Ingenuity Helicopter made its 59th flight on Mars—achieving its second highest altitude while taking pictures of this flight—the Perseverance Mars rover was watching. See two perspectives of this 142-second flight that reached an altitude of 66 feet (20 meters). This flight took place on Sept.16, 2023. 

In this side-by-side video, you will see the perspective from Perseverance on the left, which was captured by the rover’s Mastcam-Z imager from about 180 feet (55 meters) away. On the right, you will see the perspective from Ingenuity, which was taken by its downward-pointing Navigation Camera (Navcam). During Flight 59, Ingenuity hovered at different altitudes to check Martian wind patterns. The highest altitude achieved in this flight was 66 feet. At the time, that was a record for the helicopter. 

Ingenuity is the first aircraft to achieve powered, controlled flight on another planet. It has completed 66 flights since April 19, 2021. That far exceeds its originally planned technology demonstration of up to five flights. NASA’s Jet Propulsion Laboratory in Southern California built and manages operations for Ingenuity and Perseverance. Arizona State University leads the operations of the Mastcam-Z instrument on Perseverance, working in collaboration with Malin Space Science Systems in San Diego.

Mars: Defrosting Dunes in Kaiser Crater | NASA Mars Reconnaissance Orbiter

Mars: Defrosting Dunes in Kaiser Crater | NASA Mars Reconnaissance Orbiter

The dark sand dune at the center of this observation is covered in a blanket of white seasonal ice in the winter. In this Martian springtime image, the western slope of the dune is partly defrosted.

Bright patches of frost (white in enhanced color) are clearly visible and are made up of water and carbon dioxide ices. Dark streaks of sand have flowed down the dune’s slope that sometimes covers the frost. These flows are caused by the rapid transformation of the frost from ice to gas as the sun heats the dune in the spring.

We can also see how these flows are diverted by the ripples on the dune. (The width of the cutout is around 520 meters.)

Note: Black and white images are 5 km across; enhanced color images are 1 km.

SpaceX Starship Liftoff & Hot-staging Separation | SpaceX Starbase in Texas

SpaceX Starship Liftoff & Hot-staging Separation | SpaceX Starbase in Texas









These are close-up views of Starship's liftoff, plus views of hot-staging separation between Starship and the Super Heavy Booster by tracking cameras.
"SpaceX's Starship returned to integrated flight testing with its second launch from Starbase in Texas. While it did not happen in a lab or on a test stand, it was absolutely a test. What we did with this second flight will provide invaluable data to continue rapidly developing Starship."

On November 18, 2023, Starship successfully lifted off at 7:02 a.m. CT from Starbase in Texas and achieved a number of major milestones, including all 33 Raptor engines on the Super Heavy Booster starting up successfully and, for the first time, completed a full-duration burn during ascent.

There are views here from the top of the launch tower at Starbase in Texas, providing a front row seat to watch liftoff of the world’s most powerful launch vehicle ever developed. 

SpaceX’s Starship spacecraft and Super Heavy rocket—collectively referred to as Starship—represent a fully reusable transportation system designed to carry both crew and cargo to Earth orbit, the Moon, Mars and beyond. Starship will be the world’s most powerful launch vehicle ever developed, with the ability to carry up to 150 metric tonnes to Earth orbit reusable, and up to 250 metric tonnes expendable.

"Starship is essential to both SpaceX’s plans to deploy its next-generation Starship system as well as for NASA, which will use a lunar lander version of Starship for landing astronauts on the moon during the Artemis III mission through the Human Landing System (HLS) program."

Key Starship Parameters:
Height: 120m/394ft
Diameter: 9m/29.5ft
Payload to LEO: 100 – 150 t (fully reusable)

Capabilities:
Satellites: "Starship is designed to deliver satellites further and at a lower marginal cost per launch than our current Falcon vehicles. With a payload compartment larger than any fairing currently in operation or development, Starship creates possibilities for new missions, including space telescopes even larger than the James Webb."

Raptor Engine Parameters:
Diameter: 1.3m/4ft
Height: 3.1m/10.2ft
Thrust: 230tf/500 klbf

Williamina Fleming's Triangular Wisp Nebula in Cygnus

Williamina Fleming's Triangular Wisp Nebula in Cygnus

These chaotic and tangled filaments of shocked, glowing gas are spread across planet Earth's sky toward the constellation of Cygnus as part of the Veil Nebula. The Veil Nebula itself is a large supernova remnant, an expanding cloud born of the death explosion of a massive star. Light from the original supernova explosion likely reached Earth over 5,000 years ago. The glowing filaments are really more like long ripples in a sheet seen almost edge on, remarkably well separated into the glow of ionized hydrogen atoms shown in red and oxygen in blue hues. 

Also known as the Cygnus Loop and cataloged as NGC 6979, the Veil Nebula now spans about 6 times the diameter of the full Moon. The length of the wisp corresponds to about 30 light years, given its estimated distance of 2,400 light years. Often identified as Pickering's Triangle for a director of Harvard College Observatory, it is perhaps better named for its discoverer, Scottish astronomer Williamina Fleming (1857-1911), as Fleming's Triangular Wisp.

The Horsehead Nebula in Orion

The Horsehead Nebula in Orion

Sculpted by stellar winds and radiation, a magnificent interstellar dust cloud by chance has assumed this recognizable shape. Fittingly named the Horsehead Nebula, it is about 1,500 light-years distant, embedded in the vast Orion cloud complex. About five light-years "tall," the dark cloud is cataloged as Barnard 33 and is visible only because its obscuring dust is silhouetted against the glowing red emission nebula IC 434. Stars are forming within the dark cloud. Contrasting blue reflection nebula NGC 2023, surrounding a hot, young star, is at the lower left of the full image. The featured gorgeous color image combines both narrowband and broadband images recorded using several different telescopes.
