Mysterious dark spot detected on Neptune
(CNN) — Astronomers have spotted a large and mysterious dark spot within Neptune’s atmosphere, and it has an unexpectedly bright companion.
The observation was made using the European Southern Observatory’s Very Large Telescope in Chile.
Space-based observatories such as the Hubble Space Telescope have observed vortex-like storms — which appear as dark spots — swirling in the blue planet’s atmosphere before, but it’s the first time an Earth-based telescope has seen one on Neptune.
These new observations are shedding more light on the phenomenon, according to new research published Thursday in the journal Nature Astronomy.
“Since the first discovery of a dark spot, I’ve always wondered what these short-lived and elusive dark features are,” said lead study author Patrick Irwin, professor of planetary physics at the University of Oxford, in a statement.
Gas giants and dark spots
Giant gaseous planets in our solar system, including Neptune, are known for the dark spots that appear in their atmospheres, such as Jupiter’s Great Red Spot, a centuries-old storm.
Neptune, an ice giant, has had multiple storms observed by Hubble over the years. The storms all seem to follow a pattern of appearing and disappearing over the course of two years, making them difficult to study. Voyager 2, a NASA probe launched in the 1970s, also glimpsed two dark storms on Neptune during its 1989 flyby of the planet, but those disappeared well before Hubble could observe them when it captured images of Neptune in 1994. The Great Dark Spot on Neptune, the nickname given to the largest storm witnessed by Voyager 2, was so large that it could contain Earth.
Neptune’s storms behave differently than hurricanes on Earth. The dark spots are high-pressure systems that start out stable and rotate clockwise, while hurricanes in Earth’s Northern Hemisphere are low-pressure systems that rotate counterclockwise.
What Irwin and his team sought to find out is how these massive storms on Neptune form in the first place.
Newly discovered Neptune feature
Neptune, which has a blue hue due to the methane in its atmosphere, is a frozen world with an average temperature of minus 392 degrees Fahrenheit (minus 235 degrees Celsius) and screaming winds that send frozen methane clouds across the planet at 1,200 miles per hour (1,931 kilometers per hour). It’s the most distant planet in our solar system, about 30 times father from the sun than Earth is, and this distance makes noon on Neptune look like twilight on Earth.
When Hubble discovered new dark spots on Neptune in 2018, Irwin’s team seized its chance to conduct Earth-based observations with the Very Large Telescope and its Multi Unit Spectroscopic Explorer instrument, or MUSE. The instrument allows astronomers to observe the entirety of an astronomical object all at once in different wavelengths of light, according to the European Southern Observatory.
Earth’s atmosphere tends to create a distorting effect for ground-based telescopes, but MUSE relies on a technique called adaptive optics to capture sharp images. The telescope’s mirrors, controlled by computers, can make real-time adjustments that correct any distortions caused by Earth’s atmosphere and preserve the fine details of celestial objects.
Data captured by the Very Large Telescope helped astronomers determine that the dark spots aren’t caused by gaps, or a clearing, in the clouds. Instead, the observations suggest that spots appear as darkening air particles gather beneath Neptune’s prominent atmospheric layer, where haze and ice mix together.
The MUSE instrument captured a 3D spectrum of light for Neptune and its dark spot, allowing astronomers to study the storm in detail and even make a surprise observation.
“In the process we discovered a rare deep bright cloud type that had never been identified before, even from space,” said study coauthor Michael Wong, a planetary scientist at the University of California, Berkeley, in a statement.
The unusual cloud appeared in the observation as a smaller bright spot next to the larger dark spot, and both are on the same atmospheric level. The astronomers said they are intrigued by the newly discovered feature and hope to learn more with future observations that can be conducted from Earth.
“This is an astounding increase in humanity’s ability to observe the cosmos,” Wong said. “At first, we could only detect these spots by sending a spacecraft there, like Voyager. Then we gained the ability to make them out remotely with Hubble. Finally, technology has advanced to enable this from the ground.”

'No need to terrorize us': Detroit's Grandmont residents frustrated over larcenies
DETROIT (WXYZ) — Residents in the Grandmont neighborhood on Detroit’s west side say they’re frustrated by larcenies that have occurred throughout the year. The most recent incident happened just days before the holidays.
Tamara Regan has lived in the Grandmont neighborhood for seven years. She loves the community but has been on edge throughout the last year due to larcenies and trespassing incidents.
“Break-in after break-in after break-in every night to the point where now we joke about it, who’s turn is the next,” Regan said. “There is no need to terrorize us like this.”
Last September, she caught a man jumping her fence on her home surveillance system, looking through her car windows. The man got spooked and took off. She says she has a chat with members of the neighborhood and they discuss the larcenies in the area.
This past summer, a large number of items were stolen including lawn equipment.
“At the beginning of the summer, they were jumping gates, taking lawn equipment, trying to break into homes, looking into homes, so it’s been really bad,” resident Quintin Ceasar said.
Most recently, Regan yet again caught a man stealing her package on her home surveillance last Saturday around 2 p.m. Detroit Police say multiple homes were hit in this most recent attack. Cmdr. Dietrich Lever of the 8th Precinct says they believe they have identified the individual and are looking to bring him into custody.
Detroit police say larcenies are actually down throughout the city but are slightly up in the 8th Precinct. Lever says they are aware of the incidents and are investigating. They have increased patrols and say the prowler from earlier this summer has been apprehended and charged.
“I really would encourage those people to stop doing this before somebody gets hurt. It’s unnecessary,” Regan added.
Detroit police say if you’re having packages delivered before the holidays, make sure to track them. And if you’re not home when they’re being delivered, ask a friend or neighbor to pick it up.

Grizzlies Star Ja Morant’s Playing Status vs Detroit Pistons Revealed
Coming off their exciting win against the Toronto Raptors, the Detroit Pistons are slated to take on the Grizzlies Wednesday night. Despite recently making his return to action, J.B. Bickerstaff won’t have to game plan to go against one All-Star.
After missing the Grizzlies last eight games, Ja Morant made his return to action Monday night against the Portland Trail Blazers. The All-Star guard quickly returned to form, posting 22 points and 11 assists in 23 minutes of action. Having just missed extended time, the Grizzlies seem to be proceeding with caution with their star point guard. Morant has already been ruled out for Wednesday’s matchup.
Even though Morant won’t be action, the Pistons will still have to prepare to go against a skilled point guard. Scotty Pippen Jr. has finally found a home in the NBA in Memphis, and is making the most of his opportunity. Recently starting in place of Morant, Pippen Jr. erupted for 30 points and 10 assists against the Chicago Bulls.
Aside from Pippen Jr., Desmond Bane is another player Detroit will have to watch closely with Morant on the sidelines. The sharpshooting guard will likely be a focal point in the offense as Memphis fills the void of the former No. 2 pick.
Even though they’ll be shorthanded, the Pistons are going to have their hands full with this Grizzlies team. They’ve remained competitive despite their injury, currently sitting in fifth place at the Western Conference at 11-7.
As for the Pistons, they’ll look to keep their momentum rolling as they slowly crawl back to .500.

Detroit Lions defense, ‘built off so much adversity’, embrace chase of everyday perfection
5 facts about Aaron Glenn, Detroit Lions defensive coordinator
Discover five intriguing facts about Aaron Glenn, the Detroit Lions’ defensive coordinator, from his NFL playing days to his innovative coaching strategies and leadership qualities.
There is a palpable swagger among the Detroit Lions defenders entering the final stretch of the season.
After being an Achilles heel at times over the last three seasons, Detroit’s defense has become not only a plus to pair with the best offense in the NFL but also a group that has been historically good in its own right.
The Lions defense has now played 10 straight quarters without giving up a touchdown to an opposing offense for the first time since 1983, including three straight second-half shutouts for the first time since 1980 after promptly handling Anthony Richardson and the Colts, 24-6 on Sunday.
“I don’t feel like it’s (improved) confidence, I just feel like it is our identity,” safety Kerby Joseph told the Free Press last week. “Every single week, we go out and show who we are.”
After 11 games, the Lions have the second-best scoring defense in the NFL at 16.6 points allowed per game, the second-best red-zone efficiency (60% of opponent’s red zone drives end in no points or a field goal) and have generated 19 turnovers, sixth-best in the NFL. Over the last five games, the defense has held teams to 12.6 points per game with eight turnovers forced despite losing four projected starters in the front seven (Aidan Hutchinson, Marcus Davenport, Derrick Barnes, Alex Anzalone) for extended periods because of serious injuries.
“We talked about this in training camp — it is going to take every single one of us to win a game,” Joseph said. “Injuries happen in this game, people are going to go down, that’s what football is. But this team is built off adversity.
“That’s one of the things I love most about this team, how we handle it. We built off so much adversity the past years, now we understand when guys go down, it’s the next man up.”
The Lions heavily invested in that side of the ball in the offseason after coming up a game short of the Super Bowl in 2023, and the fruits of that effort have come to bear through 11 games. The investment paired with substantial gains made by young contributors on all three levels has elevated the group to improve despite the losses of what were expected to be key contributors during training camp.
Young players like Joseph, fellow safety Brian Branch, linebacker Jack Campbell and defensive tackle Alim McNeill have all taken a step forward with their games with another year in Glenn’s system. And the additions like defensive tackle D.J. Reader and nickel cornerback Amik Robertson have allowed the young players to move around the field and turn into better playmakers, which is also a credit to the coordinator for putting guys in the right spots.
“He tells us all the time, he calls the plays but the play is only going to work because of the players,” Robertson told the Free Press. “He got those guys and he knows what guy he needs in this spot or this spot to make all of this work. And we just got the pieces and we play as a whole.”
Dan Campbell said Monday the improvements are the evidence of the players’ work and Glenn’s efforts in putting everything in order.
“He puts in the work and he’s creative,” Dan Campbell said. “He does a good job of understanding what our players do well and putting them in positions to have success and where we feel like we can have the biggest advantage on our opponent.”
Playing for each other
Amon-Ra St. Brown said last week this is the best secondary he has been around in his four years in the NFL, in part because of how close the group is and how they push each other daily.
“They don’t blink every week,” St. Brown said. “They play for each other. I think they’re tighter. For me, I’ve been here four years, the defense looks tighter than they ever have before, just friendship-wise being together.”
The secondary, one of the groups overhauled with the addition of two rookie cornerbacks, a free agent cornerback and trading for a cornerback, challenge each other every day in practice and games for better performances. One of the ways they push each other is by getting together on Thursdays of a game week to watch film and that week’s Thursday Night Football game.
“Like on Thursdays, when they’re at one person’s place and they’re watching tape, man, as a coach, you can’t ask for anything more than that,” Glenn said. “You give them the concept, ‘Here’s what we’re trying to do.’
“You make sure they understand the vision of where you’re trying to go, and then you let those guys run with it and then they start to ask questions on how we’re going to do things, and I think it’s a beautiful thing.”
The challenges, such as Branch telling Joseph he wouldn’t let a receiver catch a pass during practice, are ways for players to push the overall standard on defense higher to get more out of their teammates.
“Most of the time, we are challenging ourselves,” Joseph said. “I should want it more than he should. You should want it more for yourself more than I want it for you.
“We keep the accountability in the room. If you know you are not going 110%, you know you will stand out on film and we will call you out because that’s not how we play defense.”The approach has led to improved play from the entire secondary. Despite sitting in the bottom third in passing yards allowed, Detroit has caused havoc with 14 interceptions and has been able to clamp down in the red zone. Joseph leads the NFL with seven interceptions, Branch has created five turnovers himself and Arnold and Davis lead the NFL in man coverage snaps.
And the striving for self-improvement extends to all levels of defense, according to Jack Campbell.
“At the end of the day as a defense, we are all grown men,” Jack Campbell said. “Each individual has a choice to make. If they want to come in here and half-ass things, it’s their choice. But I feel like we have a great group of guys coming in here always wanting to improve and get better. … It starts with Dan and Brad finding the right guys to fit the culture and their vision. Usually, when you get the right guys, you don’t have to teach them all that stuff.”
Peaking late
The Lions’ defense wants to age like wine as the long NFL season progresses by marginally improving by the day. The goal, Glenn said, is to find their highest level entering the final stretch.
“Going into the end of November, going into December, man, we want to be at peak performance when it comes to how we play, so we’re trying to pair our run defense and our pass defense together and make sure we’re doing a good job of that,” Glenn said.
It’s hard to improve on what the defense did the last three games, but Robertson believes they have the margin to elevate their play.
“Working on the little things, man,” Robertson said. “The details, being able to play fast. But, I gotta say, it’s a lot of things that go into being a great defense.
“It’s about perfection and no one knows how perfection looks. That’s why, as a defense, we try to chase that each and every day.”
