Supermassive Black Holes and Their Impact on Galaxy Evolution

At the center of almost every large galaxy — including our own Milky Way — lies a supermassive black hole (SMBH) containing millions to billions of times the mass of the Sun. These enormous objects are among the most mysterious structures in the universe. While black holes themselves emit no light, the regions around them are some of the brightest and most energetic places in the cosmos

The Atmospheres of Exoplanets and the Search for Water Vapor

Over the past three decades, astronomers have discovered more than 5,500 exoplanets orbiting stars beyond our Solar System. These worlds come in all sizes — from rocky Earth-like planets to giant gas planets larger than Jupiter. While simply detecting these planets was once a major achievement, modern astronomy has gone much further: scientists can now study the atmospheres of exoplanets, looking for chemical fingerprints like water vapor, methane, carbon dioxide and oxygen

Every star in the night sky — including our Sun — was once part of a cold, dark cloud of gas and dust. These enormous clouds, called giant molecular clouds, are the birthplaces of stars and planetary systems. Over millions of years, gravity pulls matter together, forming dense cores that eventually ignite nuclear fusion and become newborn stars. Around these young stars, disks of dust and gas slowly form planets, moons, comets and asteroids

The universe began with the Big Bang about 13.8 billion years ago. In the first moments, there were no stars, no planets and no galaxies – only an expanding, hot and dense sea of particles and radiation. Over time, this chaotic early universe cooled and tiny fluctuations in density grew under gravity, eventually giving birth to the first galaxies. These primordial galaxies mark the beginning of what astronomers call the “cosmic dawn

The James Webb Space Telescope (JWST), launched on December 25, 2021, is the most powerful and advanced space telescope ever built. Designed as the successor to the Hubble Space Telescope, JWST observes the universe in infrared light, allowing scientists to see deeper into space and further back in time than ever before

Mars has always been one of the most fascinating worlds in our Solar System. Often called the "Red Planet," it is the closest planet with a real possibility of past — or even present — microbial life. Over the last five decades, NASA and other space agencies have sent orbiters, landers, rovers and even a flying helicopter to Mars to study its geology, atmosphere, climate and potential habitability

The International Space Station (ISS) is the largest and most advanced laboratory ever built in space. Orbiting Earth every 90 minutes, the ISS represents one of humanity’s greatest achievements in engineering, international cooperation and scientific discovery. Since 2000, astronauts have lived continuously aboard the ISS, making it a unique microgravity research center and a symbol of global collaboration

The Space Shuttle Era (1981–2011) represents one of NASA’s most ambitious and technologically significant periods. For 30 years, the Space Shuttle fleet – Columbia, Challenger, Discovery, Atlantis and Endeavour – carried astronauts, satellites, scientific instruments and modules into space. It was the world’s first reusable spacecraft, capable of launching like a rocket, operating like a space station and landing like an airplane

The Apollo Moon Missions represent one of humanity’s greatest achievements. Conducted by NASA between 1961 and 1972, the Apollo program successfully landed humans on the Moon, returned them safely to Earth and transformed our understanding of space exploration forever. The missions demonstrated extraordinary engineering, innovation and human courage during the height of the space race

Sending humans back to the Moon and eventually to Mars is one of the greatest goals of modern space exploration. However, long-term human missions in deep space require advanced technology, safe habitats, reliable life support systems and years of preparation. NASA’s Artemis program aims to build a sustainable human presence on the Moon, while planning the first crewed missions to Mars in the coming decades
