A galaxy with a bright heart | Hubble

This unbarred spiral galaxy NGC 5033, located about 40 million light-years away in the constellation of Canes Venatici (The Hunting Dogs). The galaxy is similar in size to our own galaxy, the Milky Way, at just over 100,000 light-years across. Like in the Milky Way NGC 5033’s spiral arms are dotted with blue regions, indicating ongoing star formation. The blue patches house hot, young stars in the process of forming, while the older, cooler stars populating the galaxy’s center cause it to appear redder in color.

In contrast to the Milky Way NGC 5033 is missing a central bar. Instead it has a bright and energetic core called an active galactic nucleus, which is powered by a supermassive black hole. This active nucleus gives it the classification of a Seyfert galaxy. Due to the ongoing activity the core of NGC 5033 shines bright across the entire electromagnetic spectrum. This released energy shows that the central black hole is currently devouring stars, dust and gas getting to close to it. As this matters falls onto the supermassive black hole, it radiates in many different wavelengths.

While its relative proximity to Earth makes it an ideal target for professional astronomer to study its active nucleus in more detail, its big apparent size on the night sky and its brightness also makes it a beautiful target for amateur astronomers.

NASA's Space to Ground: "A Successful Failure"

Week of October 19, 2018: NASA's Space to Ground is your weekly update on what's happening aboard the International Space Station.

Three Expedition 57 crew members are staying busy aboard the International Space Station after the climb to orbit of two crewmates was aborted last Thursday morning, October 11. American Nick Hague and Russian Alexey Ovchinin made an emergency landing shortly after launch, but are in excellent shape. The trio in orbit is continuing science and maintenance aboard the orbital laboratory.

NASA astronaut Hague and Roscosmos cosmonaut Ovchinin are safe and returned to Moscow with mission officials after their aborted mission. The Soyuz MS-10 rocket booster experienced a failure about two minutes after launching from the Baikonur Cosmodrome in Kazakhstan. Investigations into the cause of the failure are beginning, and the space station international partner agencies are evaluating what changes to the station’s operating plan will need to be adopted.

The three humans still orbiting Earth are safe with plenty of supplies and work to do on orbit.

NASA's Webb Telescope to Examine Active Galaxy NGC 4151

Distance: 62 million light-years
Galaxies and their central, supermassive black holes are inextricably linked. Both grow in lockstep for reasons that are not yet understood. To gain new insights, Webb will turn its infrared gaze to the center of a nearby galaxy called NGC 4151, whose supermassive black hole is actively feeding and glowing brightly. By measuring the motions of stars clustered around the black hole and comparing them to computer models, astronomers can determine the black hole’s mass. This challenging measurement will test the capabilities of Webb’s innovative instrument called an integral field unit.

NGC 4151
At first glance, the galaxy NGC 4151 looks like an average spiral. Examine its center more closely, though, and you can spot a bright smudge that stands out from the softer glow around it. That point of light marks the location of a supermassive black hole weighing about 40 million times as much as our Sun.

Astronomers will use NASA’s James Webb Space Telescope to measure that black hole’s mass. The result might seem like a piece of trivia, but its mass determines how a black hole feeds and affects the surrounding galaxy. And since most galaxies contain a supermassive black hole, learning about this nearby galaxy will improve our understanding of many galaxies across the cosmos.

“Some central questions in astrophysics are: How does a galaxy’s central black hole grow with time; how does the galaxy itself grow with time; and how do they affect each other? This project is a step toward answering those questions,” explained Misty Bentz of Georgia State University, Atlanta, the principal investigator of the project.

Probing a galaxy’s core
There are several methods of weighing supermassive black holes. One technique relies on measuring the motions of stars in the galaxy’s core. The heavier the black hole, the faster nearby stars will move under its gravitational influence.

NGC 4151 represents a challenging target, because it contains a particularly active black hole that is feeding voraciously. As a result, the material swirling around the black hole, known as an accretion disk, shines brightly. The light from the accretion disk threatens to overwhelm the fainter light from stars in the region.

“With Webb’s beautifully shaped mirrors and sharp ‘vision,’ we should be able to probe closer to the galaxy’s center even though there’s a really bright accretion disk there,” said Bentz.

The team expects to be able to investigate the central 1,000 light-years of NGC 4151, and be able to resolve stellar motions on a scale of about 15 light-years.

A thousand spectra at once
To achieve this feat, the team will use Webb’s Near-Infrared Spectrograph (NIRSpec) integral field unit, or IFU. It will be the first IFU flown in space, and it has a unique capability.

Webb’s IFU takes the light from every location in an image and splits it into a rainbow spectrum. To do this it employs almost 100 mirrors, each of them precision crafted to a specific shape, all squeezed into an instrument the size of a shoebox. Those mirrors effectively slice a small square of the sky into strips, then spread the light from those strips out both spatially and in wavelength.

In this way a single image yields 1,000 spectra. Each spectrum tells astronomers not only about the elements that make up the stars and gas at that exact point of the sky, but also about their relative motions.

Despite Webb’s exquisite resolution, the team won’t be able to measure the motions of individual stars. Instead, they will get information about groups of stars very close to the center of the galaxy. They will then apply computer models to determine the gravitational field affecting the stars, which depends on the size of the black hole.

“Our computer code generates a bunch of mock stars—tens of thousands of stars, mimicking the motions of real stars in the galaxy. We put in a variety of different black holes and see what matches the observations the best,” said Monica Valluri of the University of Michigan, a co-investigator on the project.

The result of this technique will be compared with a second one that focuses on the gas at the galaxy’s center, rather than the stars.

“We should get the same answer, no matter what technique we use, if we’re looking at the same black hole,” said Bentz. “NGC 4151 is one of the best targets for making that comparison.”

These observations will be taken as part of the Director’s Discretionary-Early Release Science program. The DD-ERS program provides time to selected projects enabling the astronomical community to quickly learn how best to use Webb’s capabilities, while also yielding robust science.

The James Webb Space Telescope will be the world's premier space science observatory. Webb will solve mysteries of our solar system, look beyond to distant worlds around other stars, and probe the mysterious structures and origins of our universe and our place in it. Webb is an international project led by NASA with its partners, the European Space Agency (ESA) and the Canadian Space Agency (CSA).

New Simulation Creates "Pulsar in a Box" | NASA Goddard

Scientists studying what amounts to a computer-simulated "pulsar in a box" are gaining a more detailed understanding of the complex, high-energy environment around spinning neutron stars, also called pulsars. The model traces the paths of charged particles in magnetic and electric fields near the neutron star, revealing behaviors that may help explain how pulsars emit gamma-ray and radio pulses with ultraprecise timing.

A pulsar is the crushed core of a massive star that exploded as a supernova. The core is so compressed that more mass than the Sun's squeezes into a ball no wider than Manhattan Island in New York City. This process also revvs up its rotation and strengthens its magnetic and electric fields.

Various physical processes ensure that most of the particles around a pulsar are either electrons or their antimatter counterparts, positrons. To trace the behavior and energies of these particles, the researchers used a comparatively new type of pulsar model called a "particle in cell" (PIC) simulation.

The PIC technique lets scientists explore the pulsar from first principles, starting with a spinning, magnetized neutron star. The computer code injects electrons and positrons at the pulsar's surface and tracks how they interact with the electric and magnetic fields. It's computationally intensive because the particle motions affect the fields and the fields affect the particles, and everything is moving near the speed of light.

The simulation shows that most of the electrons tend to race outward from the magnetic poles. Some medium-energy electrons scatter wildly, even heading back to the pulsar.

The positrons, on the other hand, mostly flow out at lower latitudes, forming a relatively thin structure called the current sheet. In fact, the highest-energy positrons here—less than 0.1 percent of the total—are capable of producing gamma rays similar to those detected by NASA's Fermi Gamma-ray Space Telescope, which has discovered 216 gamma-ray pulsars.

The simulation ran on the Discover supercomputer at NASA's Center for Climate Simulation at NASA's Goddard Space Flight Center in Greenbelt, Maryland, and the Pleiades supercomputer at NASA's Ames Research Center in Silicon Valley, California. The model actually tracks "macroparticles," each of which represents many trillions of electrons or positrons.

Hurricane Michael Makes Landfall | NOAA

Oct. 10, 2018: Early Wednesday afternoon, powerful Hurricane Michael made landfall along the Florida Panhandle as a record-setting Category 4 storm. The National Hurricane Center reported Michael's sustained winds were near 155 mph as the eye of the storm moved ashore near Mexico City, Florida at 1:30 p.m. ET October 10. According to NOAA's historical hurricane tracks database, Michael is the first Category 4 storm to make landfall along the Florida Panhandle since records began in 1851.

This GOES East satellite imagery shows Hurricane Michael just as the storm made landfall at 1:30 p.m. ET October 10.

Michael is expected to drop heavy rains across the Florida Panhandle, southeast Alabama and portions of southwest and central Georgia, with widespread totals of 4 to 8 inches expected. As the storm moves inland through the southeastern U.S., the storm will produce 3 to 6 inches of rain across northern Georgia, the Carolinas and southern Virginia.

This geocolor-enhanced imagery was created by NOAA's partners at the Cooperative Institute for Research in the Atmosphere. The GOES East geostationary satellite, also known as GOES-16, provides coverage of the Western Hemisphere, including the United States, the Atlantic Ocean and the eastern Pacific. The satellite's high-resolution imagery provides optimal viewing of severe weather events, including thunderstorms, tropical storms and hurricanes.

NASA's Space to Ground: Hello, Goodbye | Week of Oct 5, 2018

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

Three crew members who have been living and working aboard the International Space Station have landed safely in Kazakhstan.

Expedition 56 Commander Drew Feustel and Flight Engineer Ricky Arnold of NASA, along with Flight Engineer and Soyuz Commander Oleg Artemyev of the Russian space agency Roscosmos landed at 7:44 a.m. EDT (5:44 p.m. in Kazakhstan) southeast of the remote town of Dzhezkazgan in Kazakhstan.

The crew completed hundreds of experiments during its 197-day expedition. Highlights included an investigation to study ultra-cold quantum gases using the first commercial European facility for microgravity research, and a system that uses surface forces to accomplish liquid-liquid separation.

Expedition 57 continues station research and operations with a crew comprised of Serena Auñón-Chancellor of NASA, Alexander Gerst of ESA (European Space Agency) and Sergey Prokopyev of Roscosmos. Gerst assumed command of the station as Feustel prepared to depart.

NASA astronaut Nick Hague and Roscosmos cosmonaut Alexey Ovchinin are scheduled to launch Oct. 11 for a same-day arrival, increasing the crew size to five.
