Lyrids Meteor Shower: How to Watch, Peak Time and Weather Forecast
Our universe might be chock-full of cosmic wonder, but you can observe only a fraction of astronomical phenomena with the naked eye. Meteor showers, natural fireworks that streak brightly across the night sky, are one of them.
The latest observable meteor shower will be the Lyrids, which has been active since April 14 and is forecast to continue through April 30. The shower reaches its peak April 21 to 22, or Tuesday night into Wednesday morning.
According to NASA, the Lyrids are one of the oldest known meteor showers, and have been enjoyed by stargazers for nearly 3,000 years. Their bright, speedy streaks are caused by the dusty debris from a comet named Thatcher. They appear to spring from the constellation Lyra, which right now can be seen in the eastern sky at night in the Northern Hemisphere.
The moon will be about 27 percent full tonight, appearing as a thick crescent in the sky, according to the American Meteor Society.
To get a hint at when to best watch for the Lyrids, you can use this tool, which relies on data from the Global Meteor Network. It shows fireball activity levels in real time.
And while you gaze at the heavens, keep an eye out for other stray meteors streaking across the night sky. Skywatchers are reporting that the amount of fireballs is double what is usually seen by this point in the year.
Where meteor showers come from
There is a chance you might see a meteor on any given night, but you are most likely to catch one during a shower. Meteor showers are caused by Earth passing through the rubble trailing a comet or asteroid as it swings around the sun. This debris, which can be as small as a grain of sand, leaves behind a glowing stream of light as it burns up in Earth’s atmosphere.
Meteor showers occur around the same time every year and can last for days or weeks. But there is only a small window when each shower is at its peak, which happens when Earth reaches the densest part of the cosmic debris. The peak is the best time to look for a shower. From our point of view on Earth, the meteors will appear to come from the same point in the sky.
The Perseid meteor shower, for example, peaks in mid-August from the constellation Perseus. The Geminids, which occur every December, radiate from the constellation Gemini.
How to watch a meteor shower
Michelle Nichols, the director of public observing at the Adler Planetarium in Chicago, recommends forgoing the use of telescopes or binoculars while watching a meteor shower.
“You just need your eyes and, ideally, a dark sky,” she said.
That’s because meteors can shoot across large swaths of the sky, so observing equipment can limit your field of view.
Some showers are strong enough to produce up to 100 streaks an hour, according to the American Meteor Society, though you probably won’t see that many.
“Almost everybody is under a light-polluted sky,” Ms. Nichols said. “You may think you’re under a dark sky, but in reality, even in a small town, you can have bright lights nearby.”
Planetariums, local astronomy clubs or even maps like this one can help you figure out where to go to escape excessive light. The best conditions for catching a meteor shower are a clear sky with no moon or cloud cover, sometime between midnight and sunrise. (Moonlight affects visibility in the same way as light pollution, washing out fainter sources of light in the sky.) Make sure to give your eyes at least 30 minutes to adjust to seeing in the dark.
Ms. Nichols also recommends wearing layers, even during the summer. “You’re going to be sitting there for quite a while, watching,” she said. “It’s going to get chilly, even in August.”
Bring a cup of cocoa or tea for even more warmth. Then lie back, scan the sky and enjoy the show.
Where weather is least likely to affect your view
Storm systems sweep across the country in early spring, and some will be obscuring skies tonight. But there will still be plenty of areas with clear skies, particularly in parts of the central United States.
“The best spot is going to be in the Upper Midwest,” said Rich Bann, a meteorologist with the Weather Prediction Center.
Minnesota, Wisconsin and Iowa will offer especially good sky-viewing weather and a beach on the Great Lakes could be a nice spot to look up at the stars.
But don’t expect to view the show from Chicago, as Illinois could see some thunderstorms. The weather will be better in the Northern and Central Plains, particularly the eastern Dakotas.
High, wispy clouds are expected over the Ohio and Tennessee Valleys and into parts of the Mid-Atlantic. But, Mr. Bann said, “you may be able to see some shooting stars through thin clouds.”
Clouds will be draped across much of the Southeast and the Northeast, though there could be some clearing in Florida, Georgia, the Carolinas and Virginia. Remember, the meteors could be visible all night long. If you look outside and see clouds, try again later.
Catching the spectacle will be challenging across much of the West, particularly from Washington into Northern California, where a storm system is bringing rain and snow. That system will move east overnight.
There are likely to be some pockets of clear skies at times across southern Nevada, northwest Arizona and southwest Utah, Mr. Bann said.

More middle-class Californians cancel health coverage after losing federal aid
Facing higher premiums and the loss of federal subsidies, 374,000 people with health insurance from the state marketplace known as Covered California canceled their coverage in the first three months of the year, according to government statistics.
The cancellations amount to 19% of those who had renewed their policies on the state marketplace during open enrollment, state officials said. Those cancellations are higher than in the past three years when they ranged from 13% to 15% of those who renewed.
Jessica Altman, executive director of Covered California, attributed the jump in cancellations to the expiration of enhanced federal subsidies that caused the cost of a plan to leap for most middle-class Californians.
“We expect coverage losses to increase through the year,” she said.
Overall, Covered California had 1.8 million enrollees in February, down from 1.94 million the year before — a decline of 7%.
Altman said monthly enrollment numbers are delayed because consumers have a three-month grace period to resume their premium payments before the insurance carriers end their coverage for nonpayment.
This year, many middle-class Californians who depend on the state-run insurance marketplace created under the Affordable Care Act faced annual costs that were hundreds of dollars higher than last year because of the end of enhanced federal subsidies that began during the COVID-19 pandemic.
In 2021, Congress voted to temporarily boost the amount of subsidies Americans could receive for an ACA plan.
The law also expanded the program to families who had more money. Before that 2021 vote, only Americans with incomes below 400% of the federal poverty level — currently $62,600 a year for a single person or $128,600 for a family of four — were eligible for ACA subsidies. The 2021 vote eliminated the income cap and limited the cost of premiums for those higher-earning families to no more than 8.5% of their income.
On top of the loss of the enhanced federal subsidies, the average premium charged by insurers this year for a Covered California plan rose by more than 10% because of fast-rising medical costs.
The decline in ACA plan enrollees, however, has been greater in some other states. California has tried to keep people insured by using state tax money to fill in the gap for lower-income families.
This year, the state budgeted $190 million for premium subsidies for people with incomes of up to 165% of the federal poverty level.
In his budget plan, Gov. Gavin Newsom proposed spending $300 million on those state subsidies in 2027. That would expand the subsidies to enrollees with incomes up to 200% of the federal poverty level, or $31,920 for an individual or $66,000 for a family of four.
“We may actually see a number of Covered California enrollees paying less in 2027” because of the additional state subsidies, Altman said.
In May, Newsom also proposed in his budget that an additional $27 million in state money be used to help enrollees pay for the cost of gender-affirming care. That amount is an increase to the $30 million that he earlier proposed be spent this year and next to defray those costs for Covered California enrollees, according to state officials.
Last year, federal health officials enacted a rule that said the federally subsidized ACA plans could no longer cover gender-affirming care because it was no longer considered an “essential health benefit.”
Newsom’s proposed budget still faces debate in Sacramento and approval by the state Legislature.
The state marketplaces, created by the Affordable Care Act, also known as Obamacare, were meant to help those who don’t have access to an employer’s health insurance plan and have incomes too high to qualify for Medi-Cal, the government-paid insurance for the poor and disabled.
Because of the higher cost this year, more people are choosing the lower-priced Bronze plans. Those plans have higher co-pays and deductibles than the more expensive plans.
“We’re very concerned with the large shift to Bronze,” Altman said. “When you have higher cost-sharing, you’re more likely to defer care.”

Political play or budget fix? Competition for JPL’s management comes at a fraught moment
Weeks after Trump administration officials announced that management of NASA’s Jet Propulsion Laboratory would open to competitive bidding for the first time, questions remain as to why Caltech could lose control of the lab its researchers founded in 1936.
On one hand, observers note, high-profile delays and cost overruns on significant recent JPL projects earned sharp criticism from NASA even before the 2024 presidential election.
On the other, the second Trump administration’s record of squeezing scientific funding and attacking institutions in Democrat-led states make it difficult to consider any action separate from the charged political atmosphere, analysts say.
“My first instinct is that this [competition] isn’t necessarily a bad thing. It’s not written in stone that Caltech must run JPL, and it wouldn’t be the worst thing to have some competition for running the place,” said Casey Dreier, chief of space policy at the non-profit Planetary Society.
“That said, that requires this contract evaluation to be fair and unbiased, and this administration has no credibility in such things,” he added. “The responsibility is on NASA to earn the trust and ensure such an evaluation is open and free from political meddling. That’s almost impossible.”
JPL became part of NASA when the space agency was formed in 1958, and Caltech has been awarded the contract to run the institution outright ever since.
Its current 10-year contract with NASA, which is valued at up to $30 billion, runs through Sept. 30, 2028.
NASA Administrator Jared Isaacman announced the competition on May 22 as part of a slate of sweeping organizational changes at the space agency.
“When you step back, it is worth considering how many additional missions we could have undertaken with the resources lost to program cancellations and cost overruns over the years,” Isaacman wrote in a memo to staff. “That is the problem we must fix, so the American taxpayer and space-loving community can receive the highest scientific return on every dollar we spend at NASA.”
Competing the contract for JPL, the lone Federally Funded Research and Development Center (FFRDC) in NASA’s portfolio, was an effort to address cost-efficiency concerns, Isaacman wrote.
“This process will take several years, and I do not anticipate it having any impact on the projects underway or the location of the facilities,” he wrote. “It does, however, provide an opportunity to evaluate management costs, overhead burdens, and ideally find ways to get after the science faster and more affordably.”
In a joint statement, Caltech President Thomas F. Rosenbaum and JPL Director Dave Gallagher said the competition was “no surprise” and that a team was already in place “to ensure we are positioned for success.”
In July, NASA’s Office of Procurement held an informational event for companies and institutions interested in the upcoming FFRDC contract.
The dozens of registered attendees included universities like USC, Texas A&M University and Georgia Tech, aerospace companies such as Boeing and Lockheed Martin and nonprofit corporations like MITRE, which manages several FFRDCs, and Universities Space Research Association, a university consortium founded by the National Academy of Sciences in 1969. (SpaceX, which has been awarded more than $13 billion in NASA contracts in the last decade, was not on the list.)
“Lockheed Martin has more than 50 years of deep space exploration success with JPL, supporting landmark missions to Jupiter, Venus, Saturn, Pluto, including nearly a dozen missions to Mars,” said Bob Behnken, VP of Exploration and Technology Strategy. “We look forward to building on that unmatched partnership in the years ahead. We are closely following NASA’s review and will continue to assess how we can best contribute to the agency’s mission.”
Other attendees contacted by The Times declined to discuss their involvement.
Isaacman indicated that JPL could come under scrutiny even before he took over NASA. The billionaire entrepreneur referenced high costs at the La Cañada Flintridge institution in a memo prepared in advance of his confirmation hearings on his priorities for the space agency.
“Contract structure: Very expensive,” Isaacman wrote of JPL in a table outlining organizational issues at each of NASA’s centers. “Must increase the output and ‘time-to-science’ KPI.”
The institution has recently suffered a number of high-profile management stumbles.
After the JPL-managed Psyche mission to a metal-rich asteroid failed to meet its 2022 launch date, NASA commissioned an independent review that said internal reorganizations and personnel changes created distracted and uninformed managers and burned-out, stretched-thin staffers.
After a 2023 independent review found there was “near zero probability” of the JPL-managed Mars Sample Return mission making its proposed 2028 launch date, and “no credible” way to bring rocks back from the Red Planet within the stated budget, Isaacman’s predecessor Bill Nelson put out a call for proposals to industry and all other NASA centers, forcing JPL to compete for its own project.
After Trump’s election, Nelson announced that the final decision would be in the next administration’s hands.
The White House pushed for massive cuts to NASA’s 2026 budget that Congress overturned, and has lobbied for similarly steep cuts again this year. JPL has instituted painful cost-cutting measures of its own, reducing staffing from roughly 6,500 employees in 2023 to 4,500 last year through layoffs and attrition.
Its struggles come at a point when NASA is enthusiastically embracing private industry. Last month the agency awarded several key contracts for its upcoming lunar missions to Jeff Bezos’s Blue Origin and other private companies.
Trump has also made no secret of his willingness to punish states that haven’t voted for him through job losses. In announcing his decision to move U.S. Space Command from Colorado to Alabama, Trump acknowledged that his loss in Colorado in three presidential elections played a part in the move.
It’s impossible to consider any decision on JPL’s future separate from the administration’s track record of politically-motivated decisions, Dreier said.
“At the heart of this is why? Why now? If this is not just some rank political attack on California, what do they hope to gain from this?” Dreier said. “That deserves explanation, because the administration otherwise has no credibility here.”

Dive Into a Very Noisy Sea With Some Very Rare Whales
The Gulf of Mexico, which the Trump administration calls the Gulf of America, is one of the noisiest bodies of water in the United States. Air gun blasts are the loudest element there, according to research by scientists who monitor underwater acoustics. Shipping traffic is another major contributor.
The noise could affect the ability of Rice’s whales to find food and mates, scientists say. The chronic stress of living in a loud environment could be detrimental to their health.
