秃鹰降落在肯尼迪航天中心
2023年4月10日，NASA肯尼迪航天中心，一只美国秃鹰俯冲降落在一根杆子上。这只鹰是在筑巢季节在佛罗里达太空港定居的一对伴侣中的一员。今年，这对夫妇在肯尼迪公园路附近的一棵树上饲养了一只孤独的幼鹰，该巢穴距离车辆装配大楼约两英里。肯尼迪目前是大约20对筑巢的秃鹰的家园。
哈勃望远镜发现一个有卷须的星系
This image taken with the NASA/ESA Hubble Space Telescope shows JO204, a ‘jellyfish galaxy’ so named for the bright tendrils of gas that appear in this image as drifting lazily below JO204’s bright central bulk. The galaxy lies almost 600 million light-years away in the constellation Sextans. Hubble observed JO204 as part of a survey performed with the intention of better understanding star formation under extreme conditions. While the delicate ribbons of gas beneath JO204 may look like floating jellyfish tentacles, they are in fact the outcome of an intense astronomical process known as ram pressure stripping. Ram pressure is a particular type of pressure exerted on a body when it moves relative to a fluid. An intuitive example is the sensation of pressure you…
暴雨和大雪使图莱里湖恢复生机
Floodwater (dark blue) stands out against the vegetation in agricultural fields around Tulare Lake near Corcoran, California, in this enhanced color image taken by Landsat 8 on March 29, 2023. Heavy rain and snow in the first three months of 2023 have once again brought water to Tulare’s lakebed, but also flooding several nearby towns. 2023 has been the wettest year in the region’s history. Tulare Lake, in California’s San Joaquin Valley, was once the largest freshwater lake west of the Mississippi River. By 1920, the rivers that fed the lake were dammed and diverted for uses such as irrigation. Since then, the lakebed has been covered with farms that grow a variety of crops. See what the region looked like in March 2022. Image…
在白宫复活节滚彩蛋活动上庆祝科学
Former NASA astronaut Alvin Drew shakes hands with a guest during the White House Easter Egg Roll in this photo from Monday, April 10, 2023. The agency also brought spacewalk suits for children to see and try on, shared images of space, and conducted an egg drop experiment. Embracing the event’s “EGGucation” theme, NASA’s STEM activities even took place in space: Astronaut Woody Hoburg used a souvenir White House egg to teach children about gravity; the video was shared during the event. See more photos from the Easter Egg Roll.

X-59有了尾翼
NASA’s X-59 sits in support framing while undergoing the installation of its lower empennage, or tail section, at Lockheed Martin Skunk Works in Palmdale, California, in this image from late March 2023. Once complete, the X-59 aircraft—the centerpiece of NASA’s Quesst mission—is designed to demonstrate the ability to fly supersonic while reducing the loud sonic boom to a quiet sonic thump. The Quesst mission will then fly the X-59 over several U.S. communities to gather data on human responses to the sound generated during supersonic flight and deliver that data set to U.S. and international regulators.

舒尔茨、史努比参观NASA总部
NASA Administrator Bill Nelson (left), Jeannie Schulz, widow of Peanuts creator Charles M. Schulz, and Snoopy are all smiles during a Wednesday, April 5, 2023, visit to NASA Headquarters in Washington. As part of the visit, Schulz showed the flown Artemis I Snoopy zero gravity indicator before it goes to its final home for display at the Schulz Museum in Santa Rosa, California. Schulz was awarded a NASA Exceptional Achievement Medal by Administrator Nelson at an “Our Blue Planet” concert at the John F. Kennedy Center for the Performing Arts. Snoopy rode along as the zero-gravity indicator on NASA’s Artemis I mission as part of a partnership with the agency.

机器人比赛
Industrial-size robots built by high school teams compete against each other in a game at Rocket City Regional, Alabama’s annual FIRST Robotics Competition, in this March 16, 2018, image. At this year’s competition, more than 1,000 high school students on 50 teams from 15 states, Mexico, and Brazil will compete. NASA and its Robotics Alliance Project provide grants for high school teams and support for FIRST Robotics Competition to address the critical national shortage of students pursuing STEM careers.

巴塔哥尼亚浮游生物漩涡
Phytoplankton create rich blooms of color in the Atlantic Ocean near South America in this enhanced color image from Dec. 2, 2014. The Patagonian Shelf Break is a biologically rich patch of ocean where airborne dust from the land, iron-rich currents from the south, and upwelling currents from the depths provide a bounty of nutrients for phytoplankton. The bands of color seen here not only reveal the location of plankton, but also the dynamic eddies and currents that carry them.
