tess satellite discovered its 1st world orbiting 2 stars
Bookmarked 323 weeks ago
researchers working with data from nasas transiting exoplanet survey satellite tess have discovered the missions first circumbinary planet a world orbiting two stars the planet called toi 1338b is around 69 times larger than earth or between the sizes of neptune and saturn it lies in a system 1300 light-years away in the constellation pictorthe stars in the system make an eclipsing binary which occurs when the stellar companions circle each other in our plane of view one is about 10 more massive than our sun while the other is cooler dimmer and only one-third the suns mass toi 1338bs transits are irregular between every 93 and 95 days and vary in depth and duration thanks to the orbital motion of its stars tess only sees the transits crossing the larger star the transits of the smaller star are too faint to detect although the planet transits irregularly its orbit is stable for at least the next 10 million years the orbits angle to us however changes enough that

Bookmarked 417 weeks ago
this visualization is based on the first three-dimensional numerical model of melting snowflakes in the atmosphere developed by scientist jussi leinonen of nasa039s jet propulsion laboratory in pasadena california a better understanding of how snow melts can help scientists recognize the signature in radar signals of heavier wetter snow -- the kind that breaks power lines and tree limbs -- and could be a step toward improving predictions of this hazardthe model reproduces key features of melting snowflakes that have been observed in nature: first meltwater gathers in any concave regions of the snowflake039s surface these liquid-water regions merge as they grow and eventually form a shell of liquid around an ice core finally developing into a water drop the visualization shows a typical snowflake less than half an inch one centimeter long the snowflake is composed of individual ice crystals whose arms became entangled when they collided in the air the extremities of the arms melt first b
