The temperature of Uranus averages minus 320 degrees Fahrenheit (-195 degrees Celsius), according to NASA. Uranus holds the record for the coldest temperature ever measured in the solar system — minus 371.56 degrees F (minus 224.2 degrees C). Neptune is — on average — the coldest planet in the solar system — averaging minus 331 … Read more
As basic science teaches us, changes in temperature can result in phase transitions in materials – like when water solidifies as ice in the freezing cold. However, in some cases the temperature that triggers the change is different depending on whether the material is cooling down or warming up. This is known as a hysteresis … Read more
Sometimes astronomers and astrophysicists are working at such gigantic, mind-bending scales – in terms of both distance and time – that you can’t help but be awestruck at the new discoveries they keep coming out with. Case in point: a temperature check of the Universe in its youngest phase, just 880 million years after … Read more
Melting ice can take on different shapes depending on the temperature of the water around it, new research reveals, giving us new insights into the complex physics that underlie this deceptively complicated transition. The team behind the research created ultra-pure ‘clear’ ice for their experiments, free from bubbles and impurities, then observed the ice … Read more
The temperature on Mars is much colder than on Earth. But then, the planet is also farther from the sun. The small, barren planet also has a thin atmosphere that is 95 percent carbon dioxide. This combination of factors makes Mars a harsh and cold world whose temperature can drop to as low as minus … Read more
A huge energy- and light-producing sphere of glowing gases, the sun makes life on Earth possible. The temperature of our nearest star varies tremendously, and not in ways you might realize. So, how hot is the sun? Nuclear fusion in the core At the core of the sun, gravitational attraction produces immense pressure and temperature, … Read more
Earth formed 4.5 billion years or so ago. Ever since then, it’s been slowly cooling on the inside. While the surface and atmosphere temperatures fluctuate over the eons (and yes, those external temperatures are currently warming), the molten interior – the beating heart of our planet – has been cooling this entire time. That’s … Read more
The nine years spanning 2013-2021 all rank among the 10 hottest on record, according to an annual report a US agency released Thursday, the latest data underscoring the global climate crisis. For 2021, the average temperature across global surfaces was 1.51 degrees Fahrenheit (0.84 degrees Celsius) above the 20th-century average, making the year the … Read more
The highest temperature ever recorded in the Arctic has been officially confirmed by the United Nations’ World Meteorological Organization (WMO), sounding ”alarm bells” about climate change. The temperature, a ”Mediterranean” 100 degrees Fahrenheit (38 degrees Celsius) — which was recorded in the Siberian town of Verkhoyansk in June 2020 — was measured at the peak of … Read more
The UN on Tuesday officially recognized the 38 degrees Celsius measured in Siberia last year as a new record high for the Arctic, sounding “alarm bells” over climate change. The sweltering heat – equivalent to 100.4 degrees Fahrenheit– was seen on June 20, 2020 in the Russian town of Verkhoyansk, marking the highest temperature ever … Read more
