Jupiter is approaching Earth for the first time in nearly 60 years.
Jupiter is approaching Earth at its closest point in nearly 60 years.
According to NASA, Jupiter will make its closest approach to Earth since 1963 on Monday, coming within about 367 million miles of our planet.
Why it’s important: The event will coincide with the gas giant’s “opposite” when it orbits Earth in the opposite direction from the Sun. It will look bigger and brighter than any other time of the year.
With clear weather, Jupiter is expected to be one of the brightest objects in the sky for the next few nights.

What they’re saying: People should be able to see three or four of Jupiter’s Galilean moons with binoculars, Adam Kobleski, a research astronomer at NASA’s Marshall Space Flight Center in Huntsville, Alabama, said earlier this month. I said
• With a 4-inch or larger telescope, viewers will also be able to see Jupiter’s Great Red Spot and bands.
• “It’s worth noting that Galileo viewed these moons with 17th-century optics,” says Kobleski. Any system you choose will require a solid mount, so get one.
Jupiter reaches opposition to Earth every 13 months, though it rarely reaches opposition during its closest approach, NASA said.
Jupiter can come closer to Earth than usual because the two planets don’t orbit the Sun in perfect circles, meaning they “pass each other at varying distances throughout the year,” according to NASA.
Jupiter is approximately 600 million kilometers from Earth.
NASA’s Juno spacecraft is set to fly within 222 miles (358 km) of Jupiter’s icy Europa surface on Thursday, NASA said last week.
•The Moon is one of the best places to look for possible life in the extrasolar system, as its subsurface ocean may be habitable.
• Juno is expected to obtain the highest-resolution images ever taken of parts of Europa’s ice sheet while collecting data on the composition of its surface and interior.
NASA is set to launch a spacecraft into a small asteroid on Monday evening to try to redirect it.
Why it matters: The first mission of its kind—called DART—marks the first real test of whether NASA will one day be able to push a potentially dangerous asteroid off a collision course with Earth if the need arises.
• “This is without a doubt the first time we have been able to demonstrate that we not only know the risks presented by asteroids and comets left, but also the ability to assess those threats, “over from the formation of the Solar System, but that we also have the technology to do that. “Take one out of the way to impact Earth,” NASA’s planetary defense officer, Lindley Johnson, said during a press conference last week.
What’s happening: DART’s target is Dimorphos, an asteroid moon orbiting the large asteroid Didymos. (None of these asteroids is dangerous to Earth.)
• The probe is expected to hit Dimorphos on Monday at 7:14 pm ET. (You can see it live here on NASA TV.)
Scientists will use other telescopes to measure how much Dimorphos orbits Didymos. The Hubble Space Telescope and the James Webb Space Telescope will also be watching the system to see if they can observe the impact.
•Mission managers must obtain images of the impactor as it approaches Dimorphos until it collides with the asteroid.
The big picture: Until now, an asteroid destroying a city or planet on a collision course with Earth has been the stuff of blockbuster movies.
But it is possible that one of these giant space rocks could be found hurtling toward our planet one day.
•NASA’s DART mission will provide scientists and engineers with key data on how to potentially scale up the technology to remove asteroids if ever needed.
Because of Tropical Storm Isaac, NASA has delayed the launch of the Moon rocket Ian
NASA will push back its latest attempt to launch its new moon rocket because of a tropical storm that could become a major hurricane, the agency said in a statement on Saturday.
The delay comes as Tropical Storm Ian is expected to strengthen into a hurricane by Monday and hit Florida’s Gulf Coast. Tuesday was originally the launch date.
This will be the third delay after a hydrogen fuel leak and other technical issues due to the first two scrubs.
To ensure that the agency completes a safe roll in time to protect its staff, they are saying that “the agency is taking a step-by-step approach to its decision-making process.” and meet regulatory requirements. the needs of their families.” “If weather forecasts improve, the option to move forward with another launch opportunity in the current window,” NASA said,
What’s next: NASA may attempt a launch on Oct. 2, the final opportunity before a two-week shutdown.
But if NASA pulls the rocket off the launch pad — decision managers will make late Sunday or early Monday — it would likely mean a long delay for the test flight, possibly until November. Pushing in, writes AP.
Tropical Storm Ian is poised to become a Category 4 hurricane, threatening Florida.
Tropical Storm Ian, which formed over the southern Caribbean on Friday night, is set to intensify into a powerful hurricane over the next few days.
The Big Picture: The National Hurricane Center is now forecasting that Ian will strengthen to a Category 4 storm within the next 72 hours. Ian’s path is still forecast to cross parts of Cuba and then turn northward into Florida by midweek.
•Ian has an abundant supply of deep, warm water ahead, which computer models show will help the storm accelerate.
• Also, starting later today, little significant wind is forecast to affect the storm.
Shear occurs when winds move in different directions or speeds with height and can prevent tropical cyclones from intensifying.
Zoom in: As of 5 p.m. ET, Tropical Storm Ian was located about 255 miles south of Kingston, Jamaica, and moving west at 16 mph. The maximum sustained winds were at 45 mph.
Grand Cayman Island is under a hurricane warning, and Little Cayman Island is under a tropical storm watch. A previous tropical storm watch issued for Jamaica has been canceled as the storm is now expected to miss the island.
The most recent NHC projections indicate that Ian will make landfall on Florida’s west coast on Thursday afternoon. The NHC did issue a warning on Saturday, noting that “the track forecast uncertainty is higher than typical.”
• “Whatever Ian’s exact route, Florida residents could see dangerous storm surge, hurricane-force gusts, and heavy rain until the middle of next week.” are sure to make sure they have them.” Have their hurricane plan in place, follow any advice from local authorities, and keep a close eye on forecast updates, “the advisory said at 5 p.m.
Although computer models disagree on the exact track and intensity forecast after Monday, the storm remains a significant threat to Florida.
• The prospect of a major hurricane hitting Florida in the next several days raises alarm bells, especially because of the array of decisions leaders must make to successfully evacuate dangerous areas such as the Florida Keys.
• In response to the approaching storm, NASA scrapped its plan for a moon rocket launch from Cape Canaveral on Tuesday. It takes three days to transport a massive rocket to the vehicle assembly building.
• Florida Gov. Ron DeSantis (R) has already declared a state of emergency for 24 counties affected by the storm.
Between the lines: According to the hurricane center’s Saturday morning report, storm track projections for days four and five typically contain inaccuracies of roughly 150 and 200 miles, respectively.
• Differences between computer models concern the strength and placement of a dip in the jet stream, also known as a trough, forecast to develop over the central and eastern United States early in the week.
• The European model shows the storm gaining strength and moving north-northeastward over time, over western Cuba and over central or southern Florida late Tuesday into Wednesday and Thursday.
• The central U.S. model, known as the GFS, is depicting another scenario, with a weaker ion turning later, threatening areas further north in the eastern Gulf of Mexico. Is.
• Forecasters with the National Oceanic and Atmospheric Administration (NOAA) are flying research aircraft in and around the ocean to feed more data into computer models, hoping to produce more accurate forecasts.
Yes, but: Despite the uncertainty, forecasters are urging Floridians to prepare for potentially significant hurricane impacts this weekend, including heavy rains and damaging winds. And storm surges can cause flooding.
• Millions of Floridians who have moved to the state in recent years may never have experienced a direct hit by a major hurricane of Category 3 intensity or greater, notably in weaker urban centers like Miami and Tampa.
Hurricanes are becoming more intense and damaging due to human-caused climate change, causing them to dump heavier amounts of rain and be stronger further north.
•Rising sea levels from melting ice sheets make hurricanes more damaging.
• In addition, there is an observed trend toward a higher proportion of storms in some ocean basins that reach the higher end of the intensity scale, and that also tend to intensify faster. However, the overall number of tropical cyclones and hurricanes is not expected to increase in a warming world.
• So far, dire predictions for this Atlantic hurricane season haven’t panned out in terms of storm activity, but that appears to be changing quickly.
Florida is on alert as Ian continues to grow into a hurricane.
The National Hurricane Center said Monday that Tropical Storm Ian had strengthened to a hurricane — and warned that it could rapidly intensify as it moves toward Florida.
Ian—which could strengthen into an advanced Category 4 storm by early midweek—was about 240 miles southeast of the western tip of Cuba at 11 a.m. ET. Jupiter is approaching Earth
• Its maximum sustained winds strengthened to 80 mph, with gusts of 45 mph Sunday afternoon, according to the NHC.
A hurricane warning was in effect for Grand Cayman and several provinces in Cuba as the storm moved northwest at 13 mph.
Tampa Bay and the rest of Florida’s west coast are under a hurricane watch. A tropical storm warning has been issued for the lower Florida Keys, the Seven Mile Bridge westward from Key West to the Dry Tortugas, as well as several provinces in Cuba.
• The NHC said in an update that it is “concerned about the predicted slow motion during this period, as the upper trough passes north and east of Ion and the steering currents weaken.”, which “potentially prolongs storm surge, wind, and rainfall impacts along affected portions of Florida’s west coast.”
The big picture: On Saturday night, Florida Gov. Rick Scott and President Biden proclaimed a federal state of emergency for several Florida counties. A state of emergency has been proclaimed by Ron DeSantis for the entire state.
What to watch for: In its update, the National Hurricane Center said Ian will become a “major hurricane” — meaning a Category 3 or higher — by Monday night or early Tuesday when it makes landfall in Cuba. It will be close to
In regions with coastal winds in the hurricane warning area, the storm surge lifted water levels to 9 to 14 feet above typical tide levels along the western Cuban coast.” The agency stated.” can.” Jupiter is approaching Earth
• The National Hurricane Center predicts two to four inches of rain from the Florida Keys to the southern and central Florida peninsula Monday through Thursday.
Studies show that human-caused climate change has led to a rapid increase in the incidence of extremes.
The western Caribbean Sea is currently a powder keg for hurricanes, with high ocean heat content and weak upper-level winds.
Even if Florida’s west coast doesn’t get a direct hit from Ian, “a hurricane doesn’t have to hit the coast or directly hit the coast to accumulate.” Jamie Rome, the temporary NHC director, said this during a briefing on Sunday. He urged Florida residents to check if they are in a possible evacuation zone at FloridaDisaster.org if an evacuation is ordered.
What’s next: The key questions facing forecasters, public officials, and tens of millions of Gulf Coast residents are where a hurricane will head once it forms and how strong it will be once it gets there.
Computer models continue to vary, with some showing landfall in northwest Florida or perhaps southeast Alabama. Others show hits farther east, near Tampa. Jupiter is approaching Earth
• Forecast trends since Friday have pushed the most likely track of Ian’s center west, near Florida’s Panhandle region.
Although the potential for significant impacts in South Florida has decreased, it is not completely over, and the Hurricane Center is urging all Floridians to be prepared for storm impacts. Jupiter is approaching Earth
Climate change brought on by human activity is altering the characteristics of nature’s most intense storms.
•For example, sea level rise from melting ice sheets makes hurricane force winds more damaging.
