On Christmas Eve 2021, a meteor struck Mars, shaking the planet so intensely that NASA's InSight lander captured the tremblings.

Until NASA's Mars Reconnaissance Orbiter, a satellite orbiting the red planet, took pictures of the fresh impact crater, scientists had no idea where the earthquake originated. On Thursday, NASA made the discovery public.

"It was immediately clear that this is the biggest new crater we've ever seen," Ingrid Daubar, InSight impact science lead, said in a press briefing. "It's about 500 feet wide or about two city blocks across. And even though meteorites are hitting the planet all the time, this crater is more than 10 times larger than the typical new craters we see forming on Mars."

A striking glow could be seen everywhere around the new crater: boulder-sized pieces of water ice that had been thrown up during the explosion from below the surface. NASA has never discovered water this close to the <a href="https://www.wionews.com/science/ancient-bacteria-shielded-from-harsh-space-radiation-might-be-sleeping-on-martian-surface-528845">Martian equator</a>. Scientists had only before observed water ice grouped close to the poles.

The finding is encouraging for NASA's goal of sending people to Mars in the future.

Their observations from those meteor hits, which were presented in two papers and published on Thursday in the journal Science, may help resolve a long-standing conundrum about the geography of Mars.

NASA images prove a meteor crashed into Mars, triggered a massive quake

Chinese authorities have issued alerts for a possible typhoon in the south, as well as for geological disasters triggered by heavy rainfall in parts of the northern and western regions.

A tropical depression in the sea area southeast of Wanning, Hainan Province, is likely to move northwestward and strengthen into a typhoon on Friday, according to the National Meteorological Centre (NMC).

The NMC expected the typhoon to make landfall on the eastern coast of Hainan between Friday evening and Saturday morning, reports Xinhua news agency.

Until Friday evening, gales and rainstorms are likely to hit areas including parts of the South China Sea, the island of Hainan and the coast of Guangdong province, the observatory said.

The Ministry of Natural Resources and the China Meteorological Administration on Thursday issued an alert for geological disasters triggered by heavy rainfall in parts of the northern and western regions.

Authorities warned of relatively high risks of geological disasters in parts of Shanxi, Sichuan, Shaanxi and Gansu from 8 pm. Thursday to 8 p.m. Friday.

China on alert for typhoon, geological disasters

Australia suffered its hottest month ever in January when widespread heatwaves exacerbated an already devastating drought, fuelled bushfires and <a href="http://www.wionews.com/world/mass-fish-death-in-australia-government-blames-weather-change-193417">contributed to mass fish deaths</a>, officials reported Friday.

The government's Bureau of Meteorology said the mean temperature across the vast continent in January exceeded 30 degrees Celsius for the first time in recorded history.

"We saw heatwave conditions affect large parts of the country through most of the month, with records broken for both duration and also individual daily extremes," said senior bureau climatologist Andrew Watkins.

Watkins said the main immediate cause of the heat was a persistent high-pressure system in the Tasman Sea south of Australia which blocked cold fronts and cooler air from reaching country.

But he added that broader global warming trends, which have seen Australian temperatures increase by more than one degree Celsius in the last 100 years, "also contributed to the unusually warm conditions".

The bureau said rainfall was also below average for most of Australia during January, worsening an already severe drought for much of the country's east, until a late January monsoon brought flooding to the northeastern state of Queensland.

The hottest temperatures during the month were experienced in South Australia, where the mercury hit 49.5 degrees C on January 24.

Authorities said the January heatwave contributed to the deaths of more than a million fish in the Murray-Darling river system, the country's largest running through five states in the east of the country.

Meanwhile, bushfires — which are frequent summer occurrences in Australia's arid southeast — spread far into the tropical northeast of the country in January.
