They're going to confirm what we already know - IT MAY BE TOO LATE to save ourselves. How about igniting JUPITER into a 2nd Sun? Come on - NAsa - YOU are our last best hope. TheBookToEndAllBooks.com

Where did our Moon come from? Over the years, there have been several theories, but the one most scientists agree on is a collision theory. It’s likely that a Mars-sized object smashed into the Earth, creating what we now see in the sky: go.nasa.gov/3uTkYpf

If the moon is made of early Earth's crust does that mean the substance of the Moon will have clues about how Earth formed? Or has Moon changed too much since then? It doesn't have tectonic dynamics at work tho.
in reply to NASA

Nice visual. It helped me understand how this theory is even possible. Early Earth, warm and soft, pliable upon impact from a Mars sized planet.


#OTD in 2009 our Wide-field Infrared Survey Explorer (WISE) launched!
WISE's all-sky survey led to mind-expanding science including:
⚫ Uncovering millions of black holes
⭐ Discovering the coolest class of stars
💡 Imaging the most luminous galaxy

In 2020 and 2021, global atmospheric concentrations of methane – a potent greenhouse gas – surged in record growth since measurements began ~40 years ago.

This video shows global methane emissions from wetlands since 1980. Wetlands are one of the largest single methane sources.
#NASAEarth



Wetlands store massive quantities of carbon in soils. But as the climate gets warmer or wetter, microbes in the wetlands start releasing more methane into the atmosphere.

On Dec. 14 at 2pm ET, @nasa scientists are discussing their findings at #AGU22. go.nasa.gov/3UYuIcp
#NASAEarth



This fall, @nasagoddard scientists trekked through and flew over Florida marshes as part of the Blueflux project.

The team is studying the exchange of carbon and methane through mangrove ecosystems with research aircraft and scientists on the ground. 🛫 🛶go.nasa.gov/3Wjds2I
#NASAEarth



For the first time, @nasa scientists mapped global salt marsh losses and their carbon impact.

The world has lost 561 square miles (1,453 square kilometers) of marshes over the past 20 years, the team found. go.nasa.gov/3FvLcCT
#NASAEarth



In a new study, scientists used #Landsat imagery from @nasa/@usgs to track shoreline changes and dramatic wetlands losses in Louisiana from 1984 to 2020.

The state lost nearly 21 square miles of important and vulnerable wetland ecosystems every year. go.nasa.gov/3UVZHFN

Gene Cernan: “The pictures speak for themselves. We were pretty happy, pretty tired, and pretty dirty. Look at the faces and you can see the sense of satisfaction. And look at how dirty...look at how filthy we are! And hot. I guarantee you that underwear was soaked.” #Apollo50th

I love Gene Cernan! In all of his moon pics he looks dirty and happy, and that makes me feel happy, and dirty...

Farewell, Moon. 👋 #Apollo17 lifted off the lunar surface #OTD in 1972, bringing a successful end to the Apollo program. The astronauts spent nearly 22 hrs outside their lander, drove 22 mi in their rover, & collected 243 lbs of samples during a mission that lasted 12.6 days.

A new view of an old favorite!

This sparkling new image depicts a small section of the Carina Nebula, one of Hubble’s most-imaged objects. It’s about 7,500 light-years away, and busy with cosmic activity – including star birth and death!

iirc, it is also where the aliens came from in Arthur C. Clarke's Childhood's End


The Carina Nebula is included in the Caldwell Catalog, published in December 1995 – 27 years ago this month!

Stargazer Sir Patrick Moore gathered a list of cosmic targets to encourage fellow amateur astronomers to experience the night sky's wonders.

50 years ago today, Gene Cernan became the last person to stand on the Moon. Before his return to the #Apollo17 lunar module, he said: “We leave as we came and, God willing, as we shall return, with peace and hope for all mankind. Godspeed the crew of Apollo 17.” #Apollo50th

...so did someone take a roll of duct tape with them to the moon just in case, or was this repair done on earth?



Team Earth! 🌎

Water connects us all – and that couldn't be more true than with the international SWOT mission, which was jointly developed by @nasa and @CNES with contributions from @csa_asc and @spacegovuk.

Follow along! SWOT is set to launch on Dec. 15. #TrackingWorldWater

Farewell to the LRV 👋

Near the end of their last EVA, #Apollo17 astronauts Cernan and Schmitt parked the rover with its camera pointed at the LM to record its launch from the Moon. Over 3 days, they had completed 22 hours of EVAs—the most of all the Apollo missions. #Apollo50th
#NASAhistory



As part of the #Apollo17 Lunar Seismic Profiling Experiment, Harrison Schmitt and Gene Cernan pulled the pins on 8 explosive charges (on the right in the 📷) left at 8 sites, activating timers that would allow them to be exploded roughly 90 hours later. #Apollo50th
#NASAhistory


Seismometers were deployed during each of the Apollo missions that reached the lunar surface and for decades have been used to investigate the internal structure of the Moon.

📷 The lunar mass spectrometer, one of the instruments of the ALSEP, is seen in the foreground.
#NASAhistory

in reply to NASA

Decades? I thought the ALSEP packages were shut down in 1977.


One of the types of moonquakes detected, originating at moderately shallow depths of 20-30 km, can register up to a startling 5.5 on the Richter scale and can last for over 10 minutes!

More about moonquakes: go.nasa.gov/3Y0VNOQ
#NASAhistory



Four geophones connected by cables to the central station of the ALSEP were set up to record the seismic waves created by the launch of the LM, the detonation of the explosives, and any moonquakes or meteorite impacts. @NASAMoon
#NASAhistory


The heart of SWOT!

A new Earth-observing satellite will survey water on more than 90% of Earth’s surface and see our planet's water in higher definition than ever before. An instrument called the Ka-band Radar Interferometer (KaRIn) is making it possible: go.nasa.gov/3FgGMzQ
#NASAJPL



KaRIn has been designed to capture very precise measurements of the height of water in Earth’s freshwater bodies and the ocean. And unlike other satellites, it can take measurements regardless of cloud cover or time of day.

SWOT is set to launch on Dec. 15. #TrackingWorldWater
