**Environmental pollution** is the contamination of the natural environment by human activities that harm the health and well-being of living organisms. Pollution can take many forms, such as air pollution, water pollution, soil pollution, noise pollution, light pollution, and radioactive pollution. Some of the main causes of environmental pollution are fossil fuel combustion, industrial waste, agricultural runoff, deforestation, urbanization, and overpopulation. **Consequences of environmental pollution** are severe and widespread, affecting both humans and other species. Some of the major consequences are: - **Climate change**: Pollution contributes to the greenhouse effect, which traps heat in the atmosphere and alters the global climate. Climate change can lead to extreme weather events, sea level rise, melting of ice caps, loss of biodiversity, and increased spread of diseases. - **Health problems**: Pollution can cause various health problems, such as respiratory diseases, cardiovascular diseases, cancer, allergies, asthma, skin disorders, eye irritation, and neurological disorders. Pollution can also affect the immune system, reproductive system, and mental health of people. - **Ecosystem degradation**: Pollution can damage the ecosystems that provide essential services and resources for life on Earth. Pollution can reduce the productivity and diversity of plants and animals, disrupt the food chains and nutrient cycles, and threaten the survival of endangered species. Pollution can also cause habitat loss, soil erosion, water scarcity, and desertification. - **Economic losses**: Pollution can impose huge economic costs on society, such as health care expenses, environmental remediation costs, reduced crop yields, lower quality of life, and loss of tourism and recreation opportunities. Pollution can also affect the trade and competitiveness of countries, as well as the social and political stability of regions. The video will explain these causes and consequences of environmental pollution in more detail, and also suggest some possible solutions and actions that can be taken to prevent and reduce pollution. The video will also highlight the importance of environmental awareness and responsibility among individuals, communities, and governments. The video will end with a call for action to protect the environment and ensure a sustainable future for all.

NASA-supported researchers have found that ice covering Greenland is melting faster than previously thought. The action is happening out of sight, below the surface.

30 million years from now, a massive cloud of gas will collide with the Milky Way. Astronomers are studying the incoming cloud and learning more about its origin.

Arctic and Antarctic sea ice are both affected by climate change, but the two poles of Earth are behaving in intriguingly different ways.

As climate change continues to hammer Arctic sea ice, pushing back its summertime boundaries to record-high latitudes, NASA is flying an innovative airborne mission to find out how these developments will affect worldwide weather.

Almost 30 years after the Montreal Protocol put the brakes on ozone-depleting chemicals, one compound remains stubbornly and mysteriously abundant in the atmosphere. NASA scientists are tracking down the source and studying its effect on the ozone layer.

NASA revealed the first five full-color images and spectrographic data from the world's most powerful space telescope, the James Webb Space Telescope, a partnership with ESA (European Space Agency), and CSA (Canadian Space Agency). The world got its first look at the full capabilities of the mission at a live event streamed from the agency's Goddard Space Flight Center in Greenbelt, Maryland, on July 12, 2022. The event showcased these targets: - Carina Nebula: A landscape speckled with glittering stars and cosmic cliffs - Stephan’s Quintet: An enormous mosaic with a visual grouping of five galaxies - Southern Ring Nebula: A nebula with rings of gas and dust for thousands of years in all directions - WASP 96-b: A distinct signature of water in the atmosphere of an exoplanet orbiting a distant Sun-like star - SMACS 0723: The deepest and sharpest infrared image of the distant universe to date

NASA's OMG and Operation IceBridge missions are investigating the thinning of Greenland's ice sheets from both above and below.

On Sept. 24, 2023, the OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, and Security–Regolith Explorer) spacecraft returned to Earth after a seven-year journey in which it explored asteroid Bennu and collected samples from its surface. The sample has been returned to the NASA Johnson Space Center's Curation Lab to be opened, studied, and distributed to scientists around the world for decades of ground-breaking research to learn more about our planet, the solar system and the organics that may reveal more about the origins of life on Earth. The sample was publicly revealed on Oct. 11, 2023.

Animation b-roll for media and public use. NASA’s Psyche mission, scheduled to launch in October 2023, is the first to a metal-rich asteroid (also named Psyche). Attached to Psyche is an independent NASA experiment called the Deep Space Optical Communications (DSOC) technology demonstration. This reel includes animations that help explain the Psyche spacecraft, its journey to the asteroid Psyche, and DSOC. The first animation shows the Psyche spacecraft’s trajectory as it leaves Earth and flies close to Mars for what is called a gravity assist. Following that are animations featuring the components on Psyche with and without labels. The animations also depict the increased data flow from DSOC, which will test high-data-rate laser communications that could be used by future NASA missions. (DSOC will not transmit Psyche data during its technology demonstration period.) Another animation shows how the DSOC transceiver attached to Psyche interacts with systems on the ground. Psyche will launch no earlier than Oct. 12, 2023. The spacecraft will begin to orbit the asteroid Psyche in 2029.

It's the animation video of NASA showing how the astronauts performs their tasks in the outer space.

SpaceX technicians encapsulate NASA's Psyche spacecraft into the the payload fairings at the Astrotech Space Operation Facility near the agency's Kennedy Space Center in Florida on October 3rd, 2023. Psyche will launch atop a SpaceX Falcon Heavy rocket from launch complex 39A at Kennedy. Launch is targeted for October 12th, 2023. Riding with Psyche is a pioneering technology demonstration, NASA's Deep Space Optical Communication (DSOC) experiment.

Celebrating 65 years, NASA is a symbol of human creativity and exploration. NASA has consistently pushed boundaries, from the historic Apollo missions that landed the first humans on the Moon to the Space Shuttle program that built the International Space Station. Missions like Landsat and Cassini have deepened our understanding of Earth and our solar system. With NASA launching the James Webb Space Telescope, the future holds even more exciting discoveries. Throughout all these adventures, NASA's commitment to exploration and science continues to lead the way. Today, the Artemis missions herald a new chapter, aiming to return humanity to the Moon and laying robust foundations for expeditions to Mars and beyond. As we honor NASA's storied past, we anticipate a future filled with discoveries, technologies, and deep-space exploration encouraged by a new generation of dedicated explorers. Here's to NASA, commemorating 65 years of cosmic exploration, innovation, and the undying quest to expand our universal frontier

On February 24, 1987, astronomers in the southern hemisphere saw a supernova in the Large Magellanic Cloud. This new object was dubbed “Supernova 1987A” and was the brightest stellar explosion seen in over four centuries. Chandra has observed Supernova 1987A many times and the X-ray data reveal important information about this object. X-rays from Chandra have shown the expanding blast wave from the original explosion slamming into a ring of material expelled by the star before it exploded. The latest Chandra data reveal the blast wave has moved beyond the ring into a region that astronomers do not know much about. These observations can help astronomers learn how supernovas impact their environments and affect future generations of stars and planets.
