As of my last knowledge update in September 2021, NASA had not released any official video depicting a spacecraft colliding with an asteroid. However, there have been discussions and plans about potential missions to redirect or impact asteroids for scientific research and planetary defense purposes. For example, NASA's Double Asteroid Redirection Test (DART) mission is designed to deliberately impact a small moonlet of the asteroid Didymos to alter its orbit. This mission aims to demonstrate the capability to change the trajectory of an asteroid in case of a potential future threat to Earth. The impact itself is not intended to be a collision in the sense of destruction, but rather a controlled alteration of the asteroid's path. If there have been any developments or releases related to a spacecraft colliding with an asteroid since September 2021, I would not have that information. I recommend checking NASA's official website or reputable space news sources for the most up-to-date and accurate information on any such events or missions.

Certainly! In 2020, NASA's Chandra X-ray Observatory observed a phenomenon where a massive black hole shredded a passing star. This event is known as a tidal disruption event (TDE). Here's a brief overview of what happened: In a galaxy located about 375 million light-years away from Earth, a supermassive black hole with a mass millions of times that of the Sun captured and tore apart a star that came too close. As the star got too close to the black hole, the immense gravitational forces at play caused tidal forces that stretched and compressed the star. This gravitational interaction led to the star's material being stretched out into a long, thin stream known as a "tidal disruption flare." As the star's material was pulled into the black hole, it heated up and emitted intense X-ray radiation. This radiation was detected by NASA's Chandra X-ray Observatory, which is designed to observe high-energy X-rays from objects in space. The X-ray emissions provided valuable insights into the processes occurring as the star was torn apart and its material was accreted onto the black hole. Tidal disruption events like this one offer scientists a unique opportunity to study the behavior of supermassive black holes and their interactions with nearby matter. These events also contribute to our understanding of how matter behaves under the extreme gravitational conditions near black holes and provide insights into the growth and evolution of galaxies. It's important to note that my knowledge is based on information available up until September 2021, so there may have been further developments or discoveries related to this event since that time.
