Venus is the second planet from the Sun and is Earth’s closest planetary neighbor. It’s one of the four inner, terrestrial (or rocky) planets, and it’s often called Earth’s twin because it’s similar in size and density. These are not identical twins, however – there are radical differences between the two worlds. The Latest

A young planet whirling around a petulant red dwarf star is changing in unpredictable ways orbit-by-orbit. It is so close to its parent star that it experiences a consistent, torrential blast of energy, which evaporates its hydrogen atmosphere – causing it to puff off the planet. But during one orbit observed with the Hubble Space Telescope, the planet looked like it wasn’t losing any material at all, while an orbit observed with Hubble a year and a half later showed clear signs of atmospheric loss.

Chandrayaan-3: India's Next Mission to the Moon Explained" Welcome to our YouTube channel! In this video, we will be diving into the fascinating world of space exploration and shedding light on India's upcoming lunar mission, Chandrayaan-3. Chandrayaan-3 is the much-anticipated follow-up to the successful Chandrayaan-2 mission, which captured the attention of the world when it attempted to land a rover on the lunar surface. Despite encountering some challenges, the mission remained a significant milestone in India's space journey. In this video, we will explore the objectives of Chandrayaan-3 and how it aims to build upon the achievements of its predecessor. From uncovering crucial scientific data about the moon's geology, to exploring the presence of water and scouting potential landing sites, this mission holds immense promise for expanding our knowledge of Earth's closest celestial neighbor. We will also delve into the advanced technologies and instruments that will be on board the spacecraft, providing greater insights into how they will enable researchers to gather valuable data and conduct groundbreaking experiments. Furthermore, we will discuss the timeline and key components of the mission, including the launch vehicle and key players involved in its execution. By following the developments and progress of Chandrayaan-3, we can stay informed about India's contributions to the field of space exploration and the scientific advancements it aims to achieve. Join us as we embark on this exhilarating journey to explore the moon once again with Chandrayaan-3. Get ready to witness the cutting-edge technologies, the challenges faced, and the potential discoveries that await us in the vast expanse of space.

Webb often gets called the replacement for Hubble, but we prefer to call it a successor. After all, Webb is the scientific successor to Hubble; its science goals were motivated by results from Hubble. Hubble's science pushed us to look to longer wavelengths to "go beyond" what Hubble has already done. In particular, more distant objects are more highly redshifted, and their light is pushed from the UV and optical into the near-infrared. Thus observations of these distant objects (like the first galaxies formed in the Universe, for example) requires an infrared telescope. This is the other reason that Webb is not a replacement for Hubble; its capabilities are not identical. Webb will primarily look at the Universe in the infrared, while Hubble studies it primarily at optical and ultraviolet wavelengths (though it has some infrared capability). Webb also has a much bigger mirror than Hubble. This larger light collecting area means that Webb can peer farther back into time than Hubble is capable of doing. Hubble is in a very close orbit around the earth, while Webb will be 1.5 million kilometers (km) away at the second Lagrange (L2) point.

There are many galaxies besides ours, though. There are so many, we can’t even count them all yet! The looked at a small patch of space for 12 days and found 10,000 galaxies, of all sizes, shapes, and colors. Some scientists think there could be as many as galaxies in the universe.

It takes a lot of field work in challenging conditions to gather important snow data. This is the story of NASA’s last SnowEx campaign and those who participated in it. In March, scientists traveled to research sites in the northern tundra and in Fairbanks, Alaska. Ground crews looked to validate data collected from airborne instruments, while the flight crews continued collecting snow data in order to see what instruments best measure snow globally. The goal for SnowEx is to determine the best remote-sensing techniques for a potential future satellite. Snow data is extremely important and can tell us things like how much spring runoff can be expected, which is vital for water resource management.
