Paper mache is the comet. Comets can travel up to 300 miles per second so everything is really hauling here. This is such amazing stuff we are even seeing celebrity tweets. William shatner saying simply hooray. He posted this youtube video. Good luck, rosetta and philaes going to land on, i am so excited. A lot of people are excited. This remarkable achievement is the latest step in a mission that actually began a decade ago and culminated with cheers and hugs in a control room in germany. This celebration went on for a few minutes but the crew quickly got to work Monitoring Communications from the robotic probe. Philae was launched by rosetta which has been circling the comets for week. Researchers believe the comet holds clues about the dawn of our solar system, maybe even life on earth. A time capsule telling us what were conditions like when the earth itself was just forming. Thats huge. Officials say the aircraft may have bounced once before coming to rest. Scientists hope to learn more about the composition of comets and exactly how they interact with the solar wind.

Abc News ReporterMarcy Gonzalez with more from the scene in new york. Reporter 68 floors up, dangling along the side of the countrys tallest building, two window washers getting the scare of their lives when a cable on their scaffolding suddenly gave way along new york citys one World Trade Center. The cables are supposed to come down at the same speed and slack developed in the cables that were on the west side, and the scaffold, of course, went from a horizontal position which is the safe position to what you see up there, the vertical position. Reporter for nearly an hour and a half, they waited, staying tethered to the scaffolding so they wouldnt fall as rescue teams rushed to the scene, clearing the plaza below, making sure people who were there paying respects at the 9 11 memorial were safe. Finally, the dramatic rescue. Firefighters inside the iconic tower which just opened last week using diamond saws to cut through three thick layers of this glass. They cut about a 3 8 inch layer of the outer glass and again, were able to safely move that into the building. Reporter pulling one worker, then the other through the window to safety. Both men taken to a hospital to be treated for minor hypothermia. Despite the dramatic day, we are told they are otherwise okay. They were fine. They really didnt say much.

Theres an increased risk of sneaker waves and rip current so Hazardous Conditions along the coastline. Heres a view of dramatic looking western sky from the east bay hills camera.

Then during the overnight hours, we will see more widespread rain pushing inland but beginning to break up into pockets of rain and showers by 5 00 a. M. , the beginning of the morning commute. But there will be wet spots for the morning commute. It could be a slow commute as a result. Later in the morning, we will see the showers become more widely scattered and they will pretty much end by the afternoon.
