Molécula: La unidad más pequeña de una sustancia que conserva las propiedades de la sustancia principal. Una molécula puede ser un átomo individual o un grupo de átomos. El agua es una sustancia y una molécula de agua está compuesta de dos átomos de hidrógeno y uno de oxígeno. Se escribe H2O. Esa molécula de agua conserva las mismas propiedades que las de un vaso de agua. Pero si las divides en hidrógeno y oxígeno, deja de ser agua.
Luna: Un objeto natural que viaja alrededor de un objeto natural más grande. Los planetas pueden tener lunas. Los planetas enanos pueden tener lunas. ¡Incluso algunos asteroides tienen lunas! Los astrónomos los suelen llamar satélites o satélites naturales.

Nebulosa: Una nube de polvo o gas que se encuentra entre las estrellas. 
Estrella de neutrones: Una estrella muy densa, compuesta principalmente de neutrones. Posee una fuerza gravitacional muy poderosa cerca de ella, ya que toda la masa de una estrella es atraída hacia un objeto, a través de unas pocas millas.

Nube de Oort: Una cubierta esférica alrededor de nuestro sistema solar. Puede contener más de un billón de cuerpos helados. Los cometas con periodos largos (que tardan más de 200 años en dar la vuelta al sol) provienen de la Nube de Oort. 

Órbita: El trayecto curvado que realiza un planeta, satélite o nave espacial a medida que circula alrededor de otro objeto.

Discovery Alert: Webb Maps and Finds Traces of Water in an Ultra-hot Gas Giant's Atmosphere - NASA Science
That made it really exciting to finally see water features with these JWST observations,’’ said Anjali Piette, a postdoctoral fellow at the Carnegie Institution for Science and one of the authors of the new research.The discoverers: More than 100 scientists around the globe are working on early science from Webb through the Transiting Exoplanet Community Early Release Science Program led by Natalie Batalha, an astronomer at the University of California, Santa Cruz, who helped coordinate the new research. Much of this groundbreaking work is being done by early career scientists like Coulombe, Challener, Piette, and Mansfield.Proximity, both to its star and to us, helped make WASP-18 b such an intriguing target for scientists, as did its large mass. WASP-18 b is one of the most massive worlds whose atmospheres we can investigate. We want to know how such planets form and come to be where they are. This, too, has some early answers from Webb.‘‘By analyzing WASP-18b’s spectrum, we not only learn about the various molecules that can be found in its atmosphere but also about the way it formed. We find from our observations that WASP-18 b’s composition is very similar to that of its star, meaning it most likely formed from the leftover gas that was present just after the star was born,’’ Coulombe said. ‘‘Those results are very valuable to get a clear picture of how strange planets like WASP-18 b, which have no counterpart in our solar system, come to exist.’’Scientists used the James Webb Space Telescope to observe the exoplanet WASP-18 b and its star before, during and after the planet was eclipsed. By measuring the change in light when the planet travels behind the star, the planet’s brightness is revealed. From these measurements, scientists were able to make a temperature map of the planet’s day side.

What’s going on here?
When your bean plants first sprouted, they could grow without creating their own food because they had plenty of food stored away in the bean. Later, when they run out of this food, they need to create their own. 
Plants use the energy from light to convert water (from the ground) and carbon dioxide (from the soil) into sugar. This sugar is their food.
To use the energy from light, they need a special chemical called chlorophyll. Chlorophyll is like a natural solar panel—it absorbs light and creates energy.
Chlorophyll is what gives plants their green color. A plant that is using the sun for photosynthesis is green because it is using a lot of chlorophyll. 
If a plant grows without sunlight, it does not use chlorophyll. The plant you grew without light is white because it never created any chlorophyll. It wouldn’t have made sense since there was no light to be found anyway and there was still plenty of food in the bean.
Light comes in many different colors depending on its wavelength. Chlorophyll absorbs all of these colors except for the green wavelengths. This means that the green is reflected back to your eye. This is what gives chlorophyll, and plants in general, a green color.
Plants use their leaves to collect the energy from light. This is why the leaves were so much bigger on the plant that grew in the light. The plant grown in the dark did not have much of a use for them. 
What do you think would happen to the plant grown in the dark if you kept growing it for a longer period of time? What do you think would happen if you brought it into the light?

That's it!
That's all you need to do for today. Come back soon and keep updating your science log!

While the rover is coring away on Mars, collecting a diverse array of scientifically intriguing samples, mission teams here are busy designing, developing, and testing various devices to bring those samples to Earth. While we've collected samples from other objects in the solar system before (see October's asteroid sample return), this would be the first time we've retrieved samples from another planet. It requires an ambitious plan executed by multiple teams that need to achieve a number of other firsts – including the first launch from another planet.

Discovery Alert: Webb Maps and Finds Traces of Water in an Ultra-hot Gas Giant's Atmosphere - NASA Science
Temperatures there reach 5,000 degrees Fahrenheit (2,700 C).NASA/JPL-Caltech (K. Miller/IPAC)There’s an intriguing exoplanet out there – 400 light-years out there – that is so tantalizing that astronomers have been studying it since its discovery in 2009. A year for WASP-18 b, one orbit around its star (slightly larger than our Sun), takes just 23 hours. There’s nothing like it in our solar system. In addition to observatories on the ground, NASA’s Hubble, Chandra, TESS, and Spitzer space telescopes have all observed WASP-18 b, an ultra-hot gas giant 10 times more massive than Jupiter. Now astronomers have taken a look with NASA’s James Webb Space Telescope and the ‘‘firsts’’ keep coming.The discovery: Scientists identified water vapor in the atmosphere of WASP-18 b, and made a temperature map of the planet as it slipped behind, and reappeared from, its star. This event is known as a secondary eclipse. Scientists can read the combined light from star and planet, then refine the measurements from just the star as the planet moves behind it.The same side, known as the dayside, of WASP-18 b always faces the star, just as the same side of the Moon always faces Earth. The temperature, or brightness, map shows a huge change in temperature – up to 1,000 degrees – from the hottest point facing the star to the terminator, where day and night sides of the tidally-locked planet meet in permanent twilight.Researchers made a brightness map, tracing the glow from hot regions of WASP-18 b as it slipped behind, and reappeared from, its star. This event is known as a secondary eclipse. Scientists can measure the combined light from star and planet, then measure the light from just the star as the planet moves behind it. The plot is a light curve, the measured change in brightness of a star as a planet moves in front of or behind it.

Student Project: 18 Ways NASA Uses Pi | NASA/JPL Edu
Versión en EspañolWhether it's sending spacecraft to other planets, driving rovers on Mars, finding out what planets are made of or how deep alien oceans are, pi takes us far at NASA. Here are just some of the ways pi helps us explore space.Explore MoreTake the NASA Pi Day ChallengeHow Many Decimals of Pi Do We Really Need?Pi Day Challenge Lessons for EducatorsShare: What's Going 'Round for Pi Day? 

1. Parachuting on Mars While no Mars landing is exactly the same, they do share one thing in common: parachutes. Slowing down a rover or lander as it drops through the thin Martian atmosphere is imperative if engineers hope to slow the spacecraft enough to give the descent rockets time for a soft landing. NASA’s engineers take all sorts of things into consideration when designing a parachute: the mass and velocity of the spacecraft, the elevation of the landing site and the density of the atmosphere, just to name a few. Pi helps engineers determine how big the parachute needs to be in order to generate the drag needed to slow down.

2. Getting new perspectives on Saturn NASA’s Cassini spacecraft spent 13 years orbiting Saturn, discovering seas and jets of water ice on its moons, and observing its majestic rings. Twice during the mission, engineers used a technique called a pi transfer to alter the spacecraft’s orbit. With a precisely steered flyby of Saturn’s largest moon, Titan, Cassini’s orbit was flipped 180 degrees to the opposite side of the planet. (In radians, 180 degrees is equal to pi, hence the name pi transfer.) With the lighting conditions also flipped 180 degrees, from Cassini's perspective, the spacecraft was able to see Saturn and Titan in a whole new light. › Use pi like a NASA engineer to solve this puzzler!› Learn more about the image

3. Mapping unexplored (and familiar) worlds Just like Earth’s ancient explorers, when spacecraft visit other planets and worlds, they make a map. Even spacecraft that orbit familiar places, like Earth, make maps of processes scientists want to understand, such as how water flows around the globe.
