Messier 109

 

Big beautiful barred spiral galaxy Messier 109 is the 109th entry in Charles Messier's famous catalog of bright Nebulae and Star Clusters. You can find it just below the Big Dipper's bowl in the northern constellation Ursa Major. In fact, bright dipper star Phecda, Gamma Ursa Majoris, produces the glare at the upper right corner of this telescopic frame. M109's prominent central bar gives the galaxy the appearance of the Greek letter "theta", θ, a common mathematical symbol representing an angle. M109 spans a very small angle in planet Earth's sky though, about 7 arcminutes or 0.12 degrees. But that small angle corresponds to an enormous 120,000 light-year diameter at the galaxy's estimated 60 million light-year distance. The brightest member of the now recognized Ursa Major galaxy cluster, M109 (aka NGC 3992) is joined by spiky foreground stars. Three small, fuzzy bluish galaxies also on the scene, identified (top to bottom) as UGC 6969, UGC 6940 and UGC 6923, are possibly satellite galaxies of the larger barred spiral galaxy Messier 109.

Hubble Captures an Active Galactic Center

Jun 27, 2025

 

The light that the NASA/ESA Hubble Space Telescope collected to create this image reached the telescope after a journey of 250 million years. Its source was the spiral galaxy UGC 11397, which resides in the constellation Lyra (The Lyre).

At first glance, UGC 11397 appears to be an average spiral galaxy: it sports two graceful spiral arms that are illuminated by stars and defined by dark, clumpy clouds of dust.

 

What sets UGC 11397 apart from a typical spiral lies at its center, where a supermassive black hole containing 174 million times the mass of our Sun grows.

As a black hole ensnares gas, dust, and even entire stars from its vicinity, this doomed matter heats up and puts on a fantastic cosmic light show.

 

Material trapped by the black hole emits light from gamma rays to radio waves, and can brighten and fade without warning. But in some galaxies, including UGC 11397, thick clouds of dust hide much of this energetic activity from view in optical light.

Despite this, UGC 11397's actively growing black hole was revealed through its bright X-ray emission — high-energy light that can pierce the surrounding dust.

This led astronomers to classify it as a Type 2 Seyfert galaxy, a category used for active galaxies whose central regions are hidden from view in visible light by a donut-shaped cloud of dust and gas.

 

Using Hubble, researchers will study hundreds of galaxies that, like UGC 11397, harbor a supermassive black hole that is gaining mass.

The Hubble observations will help researchers weigh nearby supermassive black holes, understand how black holes grew early in the universe’s history, and even study how stars form in the extreme environment found at the very center of a galaxy.

Fiery meteor traveling 30,000 mph lands near Georgia town, NASA reveals details

Updated: 12:09 AM EDT Jun 27, 2025

 

BLACKSVILLE, Ga. — NASA has shared what they know after many people in the Southeast filed reports of a fiery ball falling from the sky on Thursday.

 

Key information:

A fiery object was seen falling from the sky around 12:21 p.m. Thursday

The meteor was traveling at a rate of 30,000 mph

The fireball was produced by an asteroidal fragment weighing about a ton

The event was reported in at least five states

The meteorite landed near Blacksville, Georgia

 

According to NASA, the object that fell from the skies landed near Blacksville, Georgia, which is in Henry County.

 

The event was seen by the GLM (Geostationary Lightning Mapper) sensors, NOAA GOES satellites, and many residents from Florida, Georgia, North Carolina, Tennessee, and South Carolina.

The fall appears in data from five different NEXRAD (Next Generation Weather Radar) and TDWR (Terminal Doppler Weather Radar) radars. A composite image of radar signatures can be found below.

 

According to Bill Cooke, lead, NASA’s Meteoroid Environments Office at the agency’s Marshall Space Flight Center in Huntsville, Alabama, the meteor was first seen at an altitude of 48 miles above the town of Oxford, Georgia, moving southwest at 30,000 miles per hour.

Cooke said the meteor disintegrated 27 miles above West Forest, Georgia, unleashing an energy of about 20 tons of TNT.

 

For comparison, the atomic bomb that was dropped on Nagasaki, nicknamed "Fat Man," had an explosive yield equivalent to 21,000 tons of TNT.

The resulting pressure wave propagated to the ground, creating booms heard by many in that area. Cooke added that the fireball was produced by an asteroidal fragment 3 feet in diameter, weighing over a ton.

 

It is also worth noting that a minor meteor shower is currently passing through the atmosphere. June Bootids typically lasts from June 11 to July 2 with its peak occurring usually around June 21, according to the American Meteor Society.

This type of meteor shower only produces strong activities on rare occasions and is typically observed with rates of one visible meteor a night. It is also best seen during the evening hours.

 

WYFF News 4 talked with Astrophysicist David Moffett, who oversees Furman University's planetarium and observatory, said, "I thought maybe this is associated with the meteor shower, like the current one, but it's not."

"The thing is that time ranges when those meteors could occur," Moffett said. "It could be associated with that meteor shower, or it could just be a completely random instance."

 

Video from White Horse Road in Greenville and from Anderson show the fireball falling from the sky at 12:21 p.m.

The National Weather Service in Charleston previously said the following "Many reports of a #fireball across the Southeast U.S.

It is not certain, but the satellite-based lightning detection shows a streak within cloud free sky over the NC/VA border, over Gasbury, VA. This streak was detected between 12:51 to 12:56 pm."

 

The WYFF News 4 newsroom started getting calls about 12:30 about a "fiery ball" falling from the sky.

David Pepper provided video from White Horse Road that shows something falling from the sky at 12:21 p.m. Watch video below. You can see it about 10 seconds into the video.

We have seen reports of the sightings in Georgia and Tennessee.

 

Earlier, the NOAA Satellite & Information Service said:

"There have been many reports of a #fireball streaking across the southeastern U.S. this afternoon!

The Geostationary Lightning Mapper (#GLM) on @NOAA's #GOES satellites can occasionally detect these bright meteors (aka #bolides) when they pass through the atmosphere.

See the quick flash #GOESEast captured around the Virginia/North Carolina border today. #GOES19"
