A Black Hole in M87? - April 5th, 1997.

"The center of nearby giant galaxy M87 is a dense and violent place. In this 1994 photograph by the Hubble Space Telescope, a disk of hot gas was found to be orbiting at the center of this massive elliptical galaxy. The disk is evident at the lower left of the picture. The rotation speed of gas in this disk indicates the mass of the object the gas is orbiting, while the size of the disk indicates an approximate volume of the central object. These observations yield a central density so high, that the only hypothesised object that could live there is a black hole. The picture also shows a highly energetic jet emanating from the central object, like a cosmic blowtorch. The jet is composed of fast-moving charged particles and has broken into knots as small as 10 light-years across."

Did you know galaxies are classified into three major categories: elliptical, spiral, and irregular? These galaxies span a wide range of sizes, from dwarf galaxies containing as few as 100 million stars to giant galaxies with more than a trillion stars: https://bit.ly/3WNI1Rd

The "afterglow" of the universe is an important piece of evidence for the Big Bang. This background radiation also provides important answers to the question of how the first galaxies were able to form. Researchers at the Universities of Bonn, Prague and Nanjing calculate that the strength of this radiation has probably been overestimated up to now. If the results prove to be accurate, it would call into question the theoretical foundation of the standard model of cosmology. The results have now been published in the journal Nuclear Physics B.

Disorder in Stephan's Quintet - December 13th, 1996.

Five closely grouped galaxies are visible in this image made using the Kitt Peak National Observatory 2.1 meter telescope. The grouping is commonly known as Stephan's Quintet. Four of the galaxies show essentially the same redshift, suggesting that they are at the same distance from us. The large bluish spiral below and left of the center actually has a smaller redshift than the others, indicating it is much closer. It is probably a foreground object which happens to lie along the line of sight to the more distant galaxies. Of the four distant galaxies, three seem to be colliding, showing serious distortions due to gravitational tidal forces. The fourth is a normal appearing elliptical galaxy (at the lower right edge of the field). Results suggest that collisions play an important role in the life cycles of galaxies.

Images to Celebrate NASA’s Chandra 25th Anniversary

These images, which all include data from Chandra, demonstrate how X-ray astronomy explores all corners of the universe. By combining X-rays from Chandra with other space-based observatories and telescopes on the ground, as many of these images do, astronomers can tackle the biggest questions and investigate long-standing mysteries across the cosmos.

On July 23, 1999, the space shuttle Columbia launched into orbit carrying Chandra, which was then the heaviest payload ever carried by the shuttle. With Commander Eileen Collins at the helm, the astronauts aboard Columbia successfully deployed Chandra into its highly elliptical orbit that takes it nearly one-third of the distance to the Moon.

X-rays are an especially penetrating type of light that reveals extremely hot objects and very energetic physical processes. Many fascinating regions in space glow strongly in X-rays, such as the debris from exploded stars and material swirling around black holes. Stars, galaxies, and even planets also give off X-rays that can be studied with Chandra.

Black Scientists and Engineers Past and Present Enable NASA Space Telescope

The Nancy Grace Roman Space Telescope is NASA’s next flagship astrophysics mission, set to launch by May 2027. We’re currently integrating parts of the spacecraft in the NASA Goddard Space Flight Center clean room.

Once Roman launches, it will allow astronomers to observe the universe like never before. In celebration of Black History Month, let’s get to know some Black scientists and engineers, past and present, whose contributions will allow Roman to make history.

Dr. Beth Brown

The late Dr. Beth Brown worked at NASA Goddard as an astrophysicist. in 1998, Dr. Brown became the first Black American woman to earn a Ph.D. in astronomy at the University of Michigan. While at Goddard, Dr. Brown used data from two NASA X-ray missions – ROSAT (the ROentgen SATellite) and the Chandra X-ray Observatory – to study elliptical galaxies that she believed contained supermassive black holes.  

With Roman’s wide field of view and fast survey speeds, astronomers will be able to expand the search for black holes that wander the galaxy without anything nearby to clue us into their presence.

Dr. Harvey Washington Banks 

In 1961, Dr. Harvey Washington Banks was the first Black American to graduate with a doctorate in astronomy. His research was on spectroscopy, the study of how light and matter interact, and his research helped advance our knowledge of the field. Roman will use spectroscopy to explore how dark energy is speeding up the universe's expansion.

NOTE - Sensitive technical details have been digitally obscured in this photograph. 

Sheri Thorn 

Aerospace engineer Sheri Thorn is ensuring Roman’s primary mirror will be protected from the Sun so we can capture the best images of deep space. Thorn works on the Deployable Aperture Cover, a large, soft shade known as a space blanket. It will be mounted to the top of the telescope in the stowed position and then deployed after launch. Thorn helped in the design phase and is now working on building the flight hardware before it goes to environmental testing and is integrated to the spacecraft.

Sanetra Bailey 

Roman will be orbiting a million miles away at the second Lagrange point, or L2. Staying updated on the telescope's status and health will be an integral part of keeping the mission running. Electronics engineer Sanetra Bailey is the person who is making sure that will happen. Bailey works on circuits that will act like the brains of the spacecraft, telling it how and where to move and relaying information about its status back down to Earth.  

 Learn more about Sanetra Bailey and her journey to NASA. 

Dr. Gregory Mosby 

Roman’s field of view will be at least 100 times larger than the Hubble Space Telescope's, even though the primary mirrors are the same size. What gives Roman the larger field of view are its 18 detectors. Dr. Gregory Mosby is one of the detector scientists on the Roman mission who helped select the flight detectors that will be our “eyes” to the universe.

Dr. Beth Brown, Dr. Harvey Washington Banks, Sheri Thorn, Sanetra Bailey, and Dr. Greg Mosby are just some of the many Black scientists and engineers in astrophysics who have and continue to pave the way for others in the field. The Roman Space Telescope team promises to continue to highlight those who came before us and those who are here now to truly appreciate the amazing science to come.

WHAT IS THE BIGGEST THING IN THE UNIVERSE??

Blog#494

Welcome back,

Saturday, April 5th, 2025.

The largest known ‘object’ in the Universe is the Hercules-Corona Borealis Great Wall.

This is a ‘galactic filament’, a vast cluster of galaxies bound together by gravity, and it’s estimated to be about 10 billion light-years across! However, this is not really a ‘celestial body’ – a term which normally implies a tightly-bound object like a star or a galaxy.

The largest known elliptical galaxy is thought to be IC 1101 (with a diameter of four million light-years), and the largest known spiral galaxy is Malin 1 (with a diameter of 650,000 light-years).

Meanwhile, the largest star by radius is thought to be UY Scuti, a red hypergiant star in the constellation of Scutum that has an estimated radius of over a billion kilometres – 1,700 times that of the Sun.
