Boeing's Starliner Spacecraft: Launchpad Arrival | NASA Kennedy

Boeing's Starliner Spacecraft: Launchpad Arrival | NASA Kennedy

The Boeing Starliner spacecraft is lifted at the Vertical Integration Facility at Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida on Tuesday, April 16, 2024. Starliner will be secured atop a United Launch Alliance Atlas V rocket for NASA’s Boeing Crew Flight Test to the International Space Station for the agency’s Commercial Crew Program. The spacecraft rolled out from Boeing's Commercial Crew and Cargo Processing Facility at NASA's Kennedy Space Center earlier in the day.

This is an important milestone ahead of the Crew Flight Test (CFT) mission launch on May 6, 2024.

Starliner will carry NASA astronauts Suni Williams and Butch Wilmore to the International Space Station for a docking to the forward port of the Harmony module. Ahead of Starliner’s launch, NASA’s SpaceX Crew-8 crewmates will board the Dragon spacecraft, currently docked to the forward port, for a relocation to the zenith port of Harmony to allow for Starliner docking. The date shift also allows additional time for the crew aboard the microgravity laboratory to complete science and cargo logistics ahead of the departure of the Dragon cargo spacecraft.

As part of the agency’s Commercial Crew Program, Starliner will launch on a United Launch Alliance Atlas V rocket from Space Launch Complex 41 at Cape Canaveral in Florida. Williams and Wilmore will spend about a week docked to the International Space Station ahead of a return to Earth in the western United States. The flight test will help NASA verify whether the Starliner system is ready to fly regular crew rotation missions to space station for the agency.

Through the Commercial Crew Program (CCP), NASA is working with business partners to build rockets and spacecraft. The Commercial Crew Program has made it possible for astronauts to launch to space from the United States once again.

Examples of Black Hole Locations in The Milky Way Galaxy | ESO Animation

This artist’s animation, done with Space Engine software, shows the locations and distances (in light-years [ly]) to examples of our galaxy’s stellar black holes: Gaia BH3, a black hole now found to be the most massive stellar black hole ever identified; Cygnus X-1, the next most massive stellar black hole; and Gaia BH1, the closest black hole to Earth. At the center of our galaxy, lurks Sagittarius A*, a supermassive black hole.

Note that, due to a projection effect, Gaia BH3 looks closer to the Sun than Gaia BH1, but in reality the former is further away. It is the second-closest black hole to Earth identified to date.

Zooming into The BH3 Black Hole System in The Milky Way Galaxy | ESO

Zooming into The BH3 Black Hole System in The Milky Way Galaxy | ESO

This video zooms into BH3, the most massive stellar black hole discovered so far in our galaxy. The black hole was detected thanks to the wobbling it induces on a companion star, seen here as a bright point at the center of the frame towards the end of the zoom. An inset at the end of the video shows an artist’s animation of what the orbits of BH (in red) and its companion star (in blue) around their common center of mass look like.

The various images shown here were taken with different telescopes at different times, and have been blended together to create this zoom. The final animation is an artistic creation.

Record-breaking Stellar Black Hole Found Nearby in the Milky Way Galaxy | ESO

Record-breaking Stellar Black Hole Found Nearby in the Milky Way Galaxy | ESO

Astronomers have found the most massive stellar black hole in our galaxy, thanks to the wobbling motion it induces on a companion star. This wobbling was measured over several years with the European Space Agency’s Gaia mission. Additional data from other telescopes, including the European Southern Observatory’s Very Large Telescope in Chile, confirmed that the mass of this black hole, dubbed Gaia BH3, is 33 times that of our Sun. The chemical composition of the companion star suggests that the black hole was formed after the collapse of a massive star with very few heavy elements, or metals, as predicted by theory. This video summarizes the discovery.

Panning over Spiral Galaxy NGC 3783 & Star HD 101274 in Centaurus | Hubble

Panning over Spiral Galaxy NGC 3783 & Star HD 101274 in Centaurus | Hubble

This image features NGC 3783, a bright barred spiral galaxy about 130 million light-years from Earth, that also lends its name to the eponymous NGC 3783 galaxy group. Like galaxy clusters, galaxy groups are aggregates of gravitationally bound galaxies. Galaxy groups, however, are less massive and contain fewer members than galaxy clusters do: where galaxy clusters can contain hundreds or even thousands of constituent galaxies, galaxy groups do not typically include more than 50. The Milky Way is actually part of a galaxy group, known as the Local Group. It contains two other large galaxies (Andromeda and the Triangulum galaxy), as well as several dozen satellite and dwarf galaxies. The NGC 3783 galaxy group, meanwhile, contains 47 galaxies. It also seems to be at a fairly early stage of its evolution, making it an interesting object of study.

Whilst the focus of this image is the spiral galaxy NGC 3783, the eye is equally drawn to the very bright object in the lower right part of this image. This is the star HD 101274. The perspective in this image makes the star and the galaxy look like close companions, but this is an illusion. HD 101274 lies only about 1,530 light-years from Earth, meaning it is about 85 thousand times closer than NGC 3783. This explains how a single star can appear to outshine an entire galaxy!

NGC 3783 is a type-1 Seyfert galaxy. This is a galaxy with a bright central region. Thus, it is particularly bright itself, as far as galaxies go. In this image it is recorded by Hubble in incredible detail, from its glowing central bar to its narrow, winding arms and the dust threaded through them, thanks to five separate images taken in different wavelengths of light. In fact, the galactic center is bright enough to Hubble that it exhibits diffraction spikes, normally only seen on stars such as HD 101274.

Image Description: A spiral galaxy, seen face-on to the viewer. The bright center of the galaxy is crossed by a glowing bar, and it is surrounded by tightly-wound spiral arms, forming a circular shape with relatively clear edges. Faraway galaxies can be seen around it, along with a few bright stars, on a dark background. One star to the right of the galaxy is very large and extremely bright with long diffraction spikes around it.

The Helix Galaxy: NGC 2685 | Gemini North Telescope

The Helix Galaxy: NGC 2685 | Gemini North Telescope

The very unusual galaxy NGC 2685, also known as the Helix Galaxy, is located about 40 million light-years away in the constellation Ursa Major. This image was captured by the Gemini North telescope, one half of the International Gemini Observatory, operated by National Science Foundation's NOIRLab. It is funded by the U.S. National Science Foundation. NGC 2685 is a peculiar lenticular galaxy known as a polar ring galaxy. A ring of gas, stars, and dust orbits NGC 2685 perpendicular to the flat plane of the host galaxy. This odd crossing of planes is believed to be evidence of galaxy interactions, mergers, or tidal accretion events.

Current research suggests that the present structure of NGC 2685 was formed when it captured material from another galaxy, which was strung out into an encircling ring. This galaxy is one of our closest known polar ring galaxies and is therefore one of the easiest of its kind to study. Owing to its odd characteristics, it has been called the most unusual galaxy in the Shapley-Ames Catalog of Bright Galaxies and appears as number 336 in astronomer Halton Arp's Atlas of Peculiar Galaxies.

The 8.1-meter diameter optical/infrared North Gemini Telescope is located on Hawaii‘s Maunakea as part of the international community of observatories built to take advantage of the superb atmospheric conditions on this long-dormant volcano that rises about 4,214 meters (13,825 feet) into the dry, stable air of the Pacific. The Gemini Observatory's international headquarters is located in Hilo, Hawai‘i at the University of Hawaii Hilo's University Park.

Since 2002 Gemini North has also been known as the Frederick C. Gillett Gemini North telescope. Dr. Gillett, who died in April 2001, was one of the primary visionaries of the Gemini telescopes. He was instrumental in assuring that the design of Gemini's twin 8-meter telescopes would make major scientific contributions to astronomy.

China Makes Progress in Developing Reusable Carrier Rockets

China Makes Progress in Developing Reusable Carrier Rockets

China successfully completed two consecutive ignition tests of a 130-tonne reusable liquid oxygen-kerosene engine on Friday, April 12, 2024, laying the foundation for maiden flights of reusable carrier rockets, said the Sixth Academy of the China Aerospace Science and Technology Corp (CASC).

Chinese engineers have overcome many technical difficulties in developing a new engine for reusable rockets. It underwent its 30th ignition test on Friday.

The engine is known as the heart of rocket that produces thrust for the lift-off. How to develop a reusable engine that can make the rocket land accurately, be more durable, and easier to repair are among the most daunting challenges facing Chinese researchers.

"First of all, it [the engine] has to be used for a long time or for multiple ignitions. The most important thing is that we must figure out the lifespan of every component and the entire machine after extremely accurate adjustment, which cannot be achieved through simulation. The only way is to have constant test runs," said Song Yaqing, who is in charge of digitalization for the liquid oxygen-kerosene engine at the 11th Institute of the Academy of Aerospace Propulsion Technology (Sixth Academy) of China Aerospace Science and Technology Corporation (CASC).

Another major problem the research team need to resolve is using what kind of materials and how to control the manufacturing process to produce an engine with high technical standards and reliable quality.

"Focusing on the requirement of technical indicators including repeatability, durability and reliability of the reusable engine, we have tackled a series of key issues and carried out a series of research projects. There were nearly 70 major research projects, which have greatly improved the technological level and stability of our engine's manufacturing process, and ensured the consistency and reliability of our products' quality," said Liu Chaofeng, a senior engineer at Xi'an Aerospace Engine Company of CASC Sixth Academy.

Planetary Nebulae HFG1 & Abell 6 in Cassiopeia

Planetary Nebulae HFG1 & Abell 6 in Cassiopeia

Planetary nebulae like Heckathorn-Fesen-Gull 1 (HFG1) and Abell 6 in the constellation Cassiopeia are remnants from the last phase of a medium sized star like our Sun. In spite of their shapes, planetary nebulae have nothing in common with actual planets. Located in the bottom left part of the featured photo, HFG1 was created by the binary star system V664 Cas. It consists of a white dwarf star and a red giant star. Both stars orbit their center of mass over about half an Earth day. Traveling with the entire nebula at a speed about 300 times faster than the fastest train on Earth, V664 Cas generates a bluish arc shaped shock wave. The wave interacts most strongly with the surrounding interstellar medium in the areas where the arc is brightest. After roughly 10,000 years, planetary nebulae become invisible due to a lack of ultraviolet light being emitted by the stars that create them. Displaying beautiful shapes and structures, planetary nebulae are highly desired objects for astrophotographers.

Planetary Nebula HFG1 in Cassiopeia | Mayall Telescope

This image was obtained with the wide-field view of the Mosaic camera on the 4-meter Mayall telescope at Kitt Peak National Observatory in Arizona. HFG1 is a planetary nebula in the constellation of Cassiopeia. It was produced by a binary star system (V664 Cas) that is moving rapidly through our Galaxy. The star is moving towards the upper-right of the image. As HFG1 plows through the interstellar medium, a bluish bowshock is produced; and a red trail of gas is left behind in its wake. The image was generated with observations in the Hydrogen alpha (red) and Oxygen [OIII] (blue) filters. In this image, North is down and East is to the right.

Distance: ~3,100 light years

The Nicholas U. Mayall Telescope is a four-meter (158 inches) reflector telescope in Arizona named after Nicholas U. Mayall. It saw first light on February 27, 1973, and was the second-largest telescope in the world at that time.

Comet 12P/Pons-Brooks over California

Comet 12P/Pons-Brooks over California

In dark evening skies over June Lake, California, northern hemisphere, planet Earth, Comet 12P/Pons-Brooks stood just above the western horizon on March 30, 2024. Its twisted turbulent ion tail and diffuse greenish coma are captured in this two degree wide telescopic field of view along with bright yellowish star Hamal also known as Alpha Arietis. Now Pons-Brooks has moved out of the northern night though, approaching perihelion on April 21. On April 8 you might still spot the comet in daytime skies. However, to do it, you will have to stand in the path of totality and look away from the spectacle of an alluring solar corona and totally eclipsed Sun.

12P/Pons–Brooks is a periodic comet with an orbital period of 71 years. It fits the classical definition of a Halley-type comet with an orbital period between 20 and 200 years. It is also one of the brightest known periodic comets, reaching an absolute visual magnitude ~5 in its approach to perihelion.

Comet Pons-Brooks was discovered at Marseilles Observatory in July 1812 by Jean-Louis Pons.

The greenish coma of this comet has become relatively easy to observe in small telescopes.
