Astronomers briefly thought Elon Musk’s car was an asteroid. Here’s why that points to a broader problem
[url=https://kra27c.cc]skraken ссылка[/url]
Seven years after SpaceX launched Elon Musk’s cherry red sports car into orbit around our sun, astronomers unwittingly began paying attention to its movements once again.
Observers spotted and correctly identified the vehicle as it started its extraterrestrial excursion in February 2018 — after it had blasted off into space during the Falcon Heavy rocket’s splashy maiden launch. But more recently, the car spawned a high-profile case of mistaken identity as space observers mistook it for an asteroid.
Several observations of the vehicle, gathered by sweeping surveys of the night sky, were inadvertently stashed away in a database meant for miscellaneous and unknown objects, according to the International Astronomical Union’s Minor Planet Center.
An amateur astronomer noticed a string of data points in January that appeared to fit together, describing the orbit of a relatively small object that was swooping between the orbital paths of Earth and Mars.
The citizen scientist assumed the mystery object was an undocumented asteroid and promptly sent his findings to the MPC, which operates at the Harvard Smithsonian Center for Astrophysics in Cambridge, Massachusetts, as a clearinghouse that seeks to catalog all known asteroids, comets and other small celestial bodies. An astronomer there verified the finding.
And thus, the Minor Planet Center logged a new object, asteroid “2018 CN41.”
Within 24 hours, however, the center retracted the designation.
The person who originally flagged the object realized their own error, MPC astronomer Peter Veres told CNN, noticing that they had, in fact, found several uncorrelated observations of Musk’s car. And the center’s systems hadn’t caught the error.
‘You get one split second’: The story behind a viral bird photo

By his own admission, James Crombie knew “very, very little” about starlings before Covid-19 struck. An award-winning sports photographer by trade, his only previous encounter with the short-tailed birds occurred when one fell into his fireplace after attempting to nest in the chimney of his home in the Irish Midlands.
“I always had too much going on with sport to think about wildlife,” said Crombie, who has covered three Olympic Games and usually shoots rugby and the Irish game of hurling, in a Zoom interview.
With the pandemic bringing major events to a halt, however, the photographer found himself at a loose end. So, when a recently bereaved friend proposed visiting a nearby lake to see flocks of starlings in flight (known as murmurations), Crombie brought along his camera — one that was conveniently well-suited to the job.
“You get one split second,” he said of the similarities between sport and nature photography. “They’re both shot at relatively high speeds and they’re both shot with equipment that can handle that.”
On that first evening, in late 2020, they saw around 100 starlings take to the sky before roosting at dusk. The pair returned to the lake — Lough Ennell in Ireland’s County Westmeath — over successive nights, choosing different vantage points from which to view the birds. The routine became a form of therapy for his grieving friend and a source of fascination for Crombie.
“It started to become a bit of an obsession,” recalled the photographer, who recently published a book of his starling images. “And every night that we went down, we learned a little bit more. We realized where we had to be and where (the starlings) were going to be. It just started to snowball from there.”
‘I’ve got something special here’
Scientists do not know exactly why starlings form murmurations, though they are thought to offer collective protection against predators, such as falcons. The phenomenon can last from just a few seconds to 45 minutes, sometimes involving tens of thousands of individual birds. In Ireland, starlings’ numbers are boosted during winter, as migrating flocks arrive from breeding grounds around Western Europe and Scandinavia.
Crombie often saw the birds form patterns and abstract shapes, their varying densities appearing like the subtle gradations of paint strokes. The photographer became convinced that, with enough patience, he could capture a recognizable shape.

Since President Donald Trump won the election in November, businesses across the globe have been bracing for higher tariffs — a key Day One promise the president made.
But over a week into his presidency, Trump has yet to enact any new tariffs.

That could change, come 11:59 p.m. ET on Saturday — the deadline Trump set for when he says he will slap 25% tariffs on all Mexican and Canadian goods and a 10% tariff on all Chinese goods.
The tariffs, he said, will be imposed as a way of punishing the three nations, which Trump claims are responsible for helping people enter the country illegally and supplying fentanyl consumed in the US.
Speaking to reporters from the Oval Office on Thursday, Trump said he meant business, especially with his tariff threats on Mexico and Canada. White House Press Secretary Karoline Leavitt also confirmed on Friday that Trump will levy the 10% tariff on China on Saturday.

Should these threats be believed? Yes and no, said Trump’s former Commerce Secretary Wilbur Ross.

The threat of blanket tariffs is likely being overstated, Ross said in an interview with CNN. “There probably will be exclusions, because there are some goods that just are not made here, will not be made here, and therefore, there’s no particular point putting tariffs on.”
Ross, who was one of a handful of initial cabinet members in Trump’s first administration who kept their position for the entire four-year term, said he advocated for such exclusions when he advised Trump on tariff policies.
