Ten mysteries of Venus
The surface of Venus is completely inhospitable for life: barren, dry, crushed under an atmosphere about 90 times the pressure of Earth's and roasted by temperatures two times hotter than an oven. But was it always that way? Could Venus once have bee.....»»
New insights into heat pathways improve understanding of fusion plasma
A high-tech fusion facility is like a thermos—both keep their contents as hot as possible. Fusion facilities confine electrically charged gas known as plasma at temperatures 10 times hotter than the sun, and keeping it hot is crucial to stoking the.....»»

To watch a comet form, a spacecraft could tag along for a journey toward the sun
Deep in the solar system, between Jupiter and Neptune, lurk thousands of small chunks of ice and rock. Occasionally, one of them will bump into Jupiter's orbit, get caught and flung into the inner solar system—towards the sun, and us......»»
Astronomers discover an inflated "hot Jupiter"
Using NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have discovered a new inflated, low-density "hot Jupiter" exoplanet. The newly found alien world, designated TIC 257060897b, is about 50 percent larger than Jupiter, but some 30 p.....»»
