Everyone is freaking out about the discovery of 7 new potentially-habitable exoplanets, but is Trappist-1 really as good as it sounds?

‘Habitable’ Exoplanets Might Not Be Very Earth-Like After All

“One of the most exciting moments in exoplanet science came in late February, when NASA’s Spitzer Space Telescope announced the discovery of seven rocky planets orbiting in or near the habitable zone of their parent star, TRAPPIST-1, which lies 40 light years away from Earth. Comparing the habitability of our own planet to the conditions on newly-discovered exoplanets, however, could be misleading, according to the authors of a commentary in the journal Nature Astronomy.”

Astronomers Aren’t Sure if TRAPPIST-1’s Planets Are Habitable After All

“In what is becoming a bit of a rollercoaster of emotions, it seems that at least a couple – if not all — of the seven planets in the TRAPPIST-1 solar system could have already been stripped of their atmosphere by the star’s radiation, making it unlikely that liquid water could flow on their surfaces after all.”

NASA Telescope Reveals Largest Batch of Earth-Size, Habitable-Zone Planets Around Single Star

“NASA’s Spitzer Space Telescope has revealed the first known system of seven Earth-size planets around a single star. Three of these planets are firmly located in the habitable zone, the area around the parent star where a rocky planet is most likely to have liquid water. The discovery sets a new record for greatest number of habitable-zone planets found around a single star outside our solar system.”

    Someone should inform NASA that this guy knows that theirs no life on Trappist-1. He's legit, hes wearing a shirt of a moon, duh.

    How cool would it be to find 3 of them in varying states of our own evolutionary past. Triassic, Stone Age, and the Dark Ages. Or any combination.

    Yes I understand the odds of finding even one with microbes.

    how much current generation spacecraft will take time to reach Trappist-1 planets ?:-)

    Well. Well keep it in our 'maybe' book. But until then.. We will just have to just watch and wait.
    And maybe, we will just have to keep looking.

    Anyone want to team up and build a starship capable of reaching speeds far greater than any space vehicles? I may have the right idea or the right kind of fuel to use to reach these speeds since space is a low pressure vacuum with no drag, we could use a special type of propellent fuel that will activate its rockets over and over again to create more thrust and more acceleration while leaving the solar system. A lightweight fuel would be more efficient and the space craft will need a new way of leaving Earth's atmosphere since we just use rockets, why not a starship that uses way less fuel to get off the planet? Plus, a lot of fuel equals better travel and having things like a computer navigator to coordinate nearby star systems and having front rocket boosters to slow down the space craft to your destination, but I would advise that if you're low on fuel and you're in a new solar system that is 16 light years from the sun, find a nearby planet (rocky if you want to mine or make fuel from its surface, gas if you want to collect helium-3, helium-4, or hydrogen gas as fuel, compress the pressures until it becomes liquid. Be sure that we would invent artificial gravity inside the starship in order to maintain our bone mass and having a sense of what's up and down. If anyone want to help fund for this project and become a part of the team, please comment now. 🙂 I'll get my bags packed, pack your bags as well as I'll make the astronaut suits for those that would love to come, tell me what size you are and I'll make them for you! You're flight will be in 10-20 years from now, so sit tight, be at the beach with girls walking in those sexy bikinis, and enjoy the sunset as stars come across and you would see the destination you will want to go in the future.

    what if you pluto haters got with the program, trace? pluto is still a planet until 3/4ths of scientists say otherwise.

    therefore , we should be grateful because the earth went through many coincidences to be here unlike these planets stuggling to make life

    But planets d,e,f are in the habitable zone and they sustain liquid water

    Well we cant actually say that these planets are lifeless until we get there or they get here, both of which are impossible lol…

Debris Disk Simulations Generate Spirals, Rings and Arcs

Published

When exoplanet scientists first spotted patterns in disks of dust and gas around young stars, they thought newly formed planets might be the cause. But a recent NASA study cautions that there may be another explanation: one that doesn’t involve planets at all.
An alternative explanation suggests the dust and gas in the disk can form the patterns themselves when they interact with starlight.
When high-energy UV starlight hits dust grains, it strips away electrons. Those electrons collide with and heat nearby gas. As the gas warms, its pressure increases and it traps more dust, which in turn heats more gas. The resulting cycle, called the photoelectric instability (PeI), can work in tandem with other forces to create some of the features astronomers have previously associated with planets in debris disks.

A 2013 study suggested PeI could explain the narrow rings seen in some disks. The model also predicted that some disks would have arcs, or incomplete rings, which weren’t directly observed in a disk until 2016.

The new simulation includes an additional new factor: radiation pressure, a force caused by starlight striking dust grains.

Light exerts a minute physical force on everything it encounters. This radiation pressure propels solar sails and helps direct comet tails so they always point away from the Sun. The same force can push dust into highly eccentric orbits, and even blow some of the smaller grains out of the disk entirely.

The new research modeled how radiation pressure and PeI work together to affect the movement of dust and gas, and also found that the two forces manifest different patterns depending on the physical properties of the dust and gas.

NASA new Discovery 2018 of World

Published

This video is about NASA’s Spitzer Space Telescope has revealed the first known system of 2018 seven Earth size planets around a single star. Three of these planets
are firmly located in the habitable zone, the area around the parent star where a rocky planet is most likely to have liquid water.

The discovery sets a new record for greatest number of habitable-zone planets found around a single star outside our solar system. All of these seven
planets could have liquid water key to life as we know it under the right atmospheric conditions, but the chances are highest with the three in the habitable
zone.
This discovery could be a significant piece in the puzzle of finding habitable environments, places that are conducive to life,” said
Thomas Zurbuchen, associate administrator of the agency’s Science Mission Directorate in Washington. Answering the question ‘are we alone’ is a top science
priority and finding so many planets like these for the first time in the habitable zone is a remarkable
step forward toward that goal Thanks for watching
