The Cassini spacecraft will crash into Saturn to save its moons

The Cassini spacecraft will crash into Saturn to save its moons But as with all things involving spaceflight, the reason for Cassini's collision course with Saturn is nothing if not practical.This means that the probe could smash into one of the planet's potentially habitable moons.

We won't know about Cassini's death at Saturn until 83 minutes after it happens

We won't know about Cassini's death at Saturn until 83 minutes after it happens One minute after the Cassini spacecraft plunges into Saturn’s atmosphere, it will die, but we won't know it until 83 minutes later.The final signal NASA scientists receive from Cassini will be a ghostly cry from a long-gone spacecraft.

Hurricane Irma again demonstrated the inferiority of the top U.S. weather model

Hurricane Irma again demonstrated the inferiority of the top U.S. weather model The National Hurricane Center accurately predicted the path of Hurricane Irma, which struck southwest Florida on Sept.But in general, the European model, which is run by the European Center for Medium-range Weather Forecasting (ECMWF), performed far better than the premiere U.

Trump calls Hurricanes Harvey and Irma the biggest storms ever, until climate change comes up

Trump calls Hurricanes Harvey and Irma the biggest storms ever, until climate change comes up And when Hurricane Irma ramped up to a Category 5 monster in the Atlantic, Trump tweeted that the storm "Looks like the largest ever recorded in the Atlantic!President, the severity of these storms — the one in Florida, the one in Texas — has that made you rethink your views of climate change?

Being rejected by robots makes people sad

Being rejected by robots makes people sad Rejection hurts, even if it's rejection from a robot.This particular Baxter was able to speak and had a screen for a face, programmed with facial expressions and even the ability to blink.

Cassini sent back its final Saturn photos, and we're not crying, you are

Cassini sent back its final Saturn photos, and we're not crying, you are The Cassini spacecraft is now feeling the inexorable tug of Saturn's gravity as the bus-sized spacecraft is being pulled down into the giant planet's cloud tops.Other photos show Titan's hazy atmosphere for the last time from close range.

Cassini, one of humanity's best spacecraft, is officially dead at Saturn

Cassini, one of humanity's best spacecraft, is officially dead at Saturn "We have loss of signal," the flight director for the mission said, as Cassini's final dispatch from Saturn ended.Scientists have been planning to send Cassini into Saturn's atmosphere for some time.

Mission controllers reacting to the end of the Cassini mission at Saturn will make you emotional

Mission controllers reacting to the end of the Cassini mission at Saturn will make you emotional Scientists aren't exactly known for their public displays of emotion, but sometimes, that's what a moment calls for.On Friday, as the long-running Cassini mission at Saturn came to a close, mission managers at NASA's Jet Propulsion Laboratory in California couldn't help but get a little teary as they said goodbye to a spacecraft that had been in space for two decades.

How Cassini Changed Our Understanding of Saturn and the Solar System

How Cassini Changed Our Understanding of Saturn and the Solar System To-date, this has been the only successful probe landing in the outer solar system.But we weren’t necessarily counting on all the surprise beauty shots that Cassini captured of Saturn and its surroundings.

Quantum Computer Cross a New Threshold

Quantum Computer Cross a New Threshold There’s been a lot of bluster surrounding quantum computers.Some say that they’re the next major step in computing, while others are more reserved about their practical applications.

Earth sends Cassini a whole lot of love after the mission comes to a bittersweet end

Earth sends Cassini a whole lot of love after the mission comes to a bittersweet end After 13 years of exploration, the Cassini spacecraft finally met its demise, hurtling itself into Saturn's atmosphere and burning up early Friday morning.And as was expected, people everywhere are mourning the loss of the iconic mission.

The Doppler effect explained using only skis and a trombone

The Doppler effect explained using only skis and a trombone So long as skiing and a trombone is involved, there is no such thing as a dull science lesson.For all of us who fell asleep during science class (I see you), the Doppler effect is the change in frequency or wavelength for a person who is moving relative to the wave source.

NASA's New Horizons Probe Wakes Up to Study Kuiper Belt

NASA's New Horizons Probe Wakes Up to Study Kuiper Belt More than three and a half billion miles away, NASA’s New Horizons probe has woken up from its long slumber, ready to take on a new mission in the outer reaches of the solar system.Now it’s on toward other Kuiper Belt objects (KBOs), which could tell us even more about the solar system than Pluto did.

Here we go again: Another hurricane, Jose, threatens the East Coast of the U.S.

Here we go again: Another hurricane, Jose, threatens the East Coast of the U.S. Tropical Storm Jose, which is forecast to re-intensify into a hurricane later on Friday, was about 485 miles southwest of Bermuda as of 11 a.The storm is forecast to gradually intensify while moving to the northwest, then north, and at some point, turn northeast parallel to the U.

Cassini's final image of Saturn shows the spot where it was doomed to die

Cassini's final image of Saturn shows the spot where it was doomed to die Just before Cassini was vaporized while falling through the extreme pressure of Saturn's clouds, the bus-sized spacecraft beamed home an image of the spot where it would meet its fate.Another gif also shows the exact spot where Cassini was expected to fall into Saturn.

After Irma, Barbuda's 300-year-old civilization 'extinguished'

After Irma, Barbuda's 300-year-old civilization 'extinguished' Ambassador Ronald Sanders, the island nation of Antigua and Barbuda's ambassador to the United States, delivered a chilling report on the status of his country in the wake of Hurricane Irma.The 400 mile-across storm entirely swallowed the 62 square mile island, and laid waste to 95 percent of the island's structures.

This pitch-black 'hot Jupiter' orbits an alien star and is darker than asphalt

This pitch-black 'hot Jupiter' orbits an alien star and is darker than asphalt A planet orbiting a star 1,400 light-years from Earth is darker than asphalt.New data from the Hubble Space Telescope shows that WASP-12b, which has a radius twice as large as Jupiter's, is an incredibly hot planet with a very low albedo—meaning that it's incredibly dark.

Ancient Meteorite Impact Produced Highest Natural Temperature Ever On Earth

Ancient Meteorite Impact Produced Highest Natural Temperature Ever On Earth This 17-mile (28-kilometer) depression contains Mistastin Lake, which is quite obviously an impact crater when seen from above.There’s an arcuate central island in the lake, which is the central uplift of the original impact crater, and the lake itself is roughly circular.
