CAPE CANAVERAL, Fla. (AP) — The Hubble Space Telescope has captured the best picture yet of a high-speed comet visiting our solar system from another star.
NASA and the European Space Agency released the latest photos Thursday.
Discovered last month by a telescope in Chile, the comet known as 3I-Atlas is only the third known interstellar object to pass our way and poses no threat to Earth.
Astronomers originally estimated the size of its icy core at several miles (tens of kilometers) across, but Hubble’s observations have narrowed it down to no more than 3.5 miles (5.6 kilometers). It could even be as small as 1,000 feet (320 meters), according to scientists.
The comet is hurtling our way at 130,000 mph (209,000 kph), but will veer closer to Mars than Earth, keeping a safe distance from both. It was 277 million miles (446 million kilometers) away when photographed by Hubble a couple weeks ago. The orbiting telescope revealed a teardrop-shaped plume of dust around the nucleus as well as traces of a dusty tail.

BERLIN (AP) — European leaders are expected to cement support for Ukraine Monday as it faces Washington’s pressure to swiftly accept a U.S.-brokered peace deal.
After Sunday’s talks in Berlin between U.S. envoys and Ukrainian President Volodymyr Zelenskyy, Ukrainian and European officials are set to continue a series of meetings in an effort to secure the continent’s peace and security in the face of an increasingly assertive Russia.
Zelenskyy sat down Sunday with U.S. President Donald Trump’s special envoy Steve Witkoff and Trump’s son-in-law Jared Kushner in the German federal chancellery in the hopes of bringing the nearly four-year war to a close.
Washington has tried for months to navigate the demands of each side as Trump presses for a swift end to Russia’s war and grows increasingly exasperated by delays. The search for possible compromises has run into major obstacles, including control of Ukraine’s eastern Donetsk region, which is mostly occupied by Russian forces.
The U.S. government late Sunday said in a social media post on Witkoff’s account after the five-hour meeting that “a lot of progress was made.”
Earlier in the day, Zelenskyy voiced readiness to drop his country’s bid to join NATO if the U.S. and other Western nations give Kyiv security guarantees similar to those offered to NATO members. But Ukraine continued to reject the U.S. push for ceding territory to Russia.
Putin wants Ukraine to withdraw its forces from the part of the Donetsk region still under its control among the key conditions for peace.
The Russian president also has cast Ukraine’s bid to join NATO as a major threat to Moscow’s security and a reason for launching the full-scale invasion in February 2022. The Kremlin has demanded that Ukraine renounce the bid for alliance membership as part of any prospective peace settlement.
Zelenskyy emphasized that any Western security assurances would need to be legally binding and supported by the U.S. Congress.
German Chancellor Friedrich Merz, who has spearheaded European efforts to support Ukraine alongside French President Emmanuel Macron and U.K. Prime Minister Keir Starmer, said Saturday that “the decades of the ‘Pax Americana’ are largely over for us in Europe and for us in Germany as well.”
“Pax Americana” refers to the U.S.’s postwar dominance as a superpower that has brought relative peace to the globe.
Merz warned that Putin’s aim is “a fundamental change to the borders in Europe, the restoration of the old Soviet Union within its borders.”
“If Ukraine falls, he won’t stop,” Merz warned during a party conference in Munich.
Macron, meanwhile, vowed Sunday on social platform X that “France is, and will remain, at Ukraine’s side to build a robust and lasting peace — one that can guarantee Ukraine’s security and sovereignty, and that of Europe, over the long term.”
Putin has denied plans to attack any European allies.
