As TIME reported in its recent special climate issue, the fires from the Amazon seen across the skies of Brazil in August “helped illuminate something the world can no longer ignore.” On the front lines of the fight to protect the land is 46-year-old Benki Pyãnko, who has experienced these significant — and devastating—changes to the environment firsthand. A ambassador of the Ashaninka people, Pyãnko has led environmental and reforesting projects in his community of Apiwtxa, inhabiting the indigenous territory of Terra Kampa do Rio Amônia in the Brazilian state of Acre, located close to the border with Peru and covered by the Amazon rainforest. There are around 3,000 Ashaninka people living across four indigenous land areas in Brazil, and over 120,000 Ashaninka living over the frontier in Peru. Pyãnko’s Apiwtxa community won the United Nations Equator Prize in 2017, a prize honoring indigenous communities, for its reforesting initiatives and defense of Ashaninka rights and culture. As ..

(CAPE CANAVERAL, Fla.) — The solar system may have another foreign guest.

Both NASA and the European Space Agency are reporting that a newly discovered comet zooming toward the sun is likely from another star. Astronomers said Thursday it’s traveling 93,000 mph (150,000 kph), so fast it likely originated outside our solar system. It’s 260 million miles (420 million kilometers) from the sun and getting closer.

It’s expected to completely sidestep Earth, remaining beyond Mars’ orbit.

Scientists predict the comet will hurtle past the sun in December and keep going until it’s back in interstellar space. It should be visible with professional telescopes well into next year. Its nucleus is estimated between 1.2 miles and 10 miles across (2 kilometers and 16 kilometers).

Officially known as C/2019 Q4, the comet was discovered two weeks ago by an amateur astronomer at an observatory on the Crimean Peninsula. In 2017, a telescope in Hawaii spied our first known interstellar visitor.
