“My mom had to leave school after 9th grade to support her family, but she always emphasized the importance of education. And with a lot of sacrifices, got us an encyclopedia in Spanish, ‘Enciclopedia de Las Ciencias’. By getting that encyclopedia for us, without knowing it, my mom was my first mentor because she introduced me to science. So that’s what helped fall in love with physics.

“I was the first of many things. I was the only one in my whole class that decided to study physics at the University of Puerto Rico at Mayagüez. I was the first master student to do a thesis related to atmospheric physics. There was no atmospheric sciences and meteorology in Puerto Rico, I saw the need and potential, so I started the first student chapter of the American Meteorological Society in Puerto Rico. I was the first one to get a PhD in atmospheric physics from the program and there have been so many firsts since then. 

“I’m leading by example. I don’t want the people who look like me to experience what I experienced because I was alone many times. And there’s a saying that says you cannot be what you can’t see.

“So, I’m not just doing science. I’m doing Science with Purpose, and my purpose is to be the voice for those who are underrepresented in science, open doors and opportunities and help them understand that they have a space in science.”

Hubble Spots a Grand Spiral of Starbursts

A close-in, face-on view of a spiral galaxy. It has two large arms that curve outward from the round, bright, central region to nearly the corners of the image. Channels of dark reddish dust that blocks light line the arms while bright pink, glowing points denote where stars are forming. Beyond its prominent spiral arms, the galaxy’s oval disk is generally cloudy in form and speckled with stars. A black background is visible behind it.

The sparkling scene depicted in this NASA/ESA Hubble Space Telescope image is of the spiral galaxy NGC 5248, located 42 million light-years from Earth in the constellation Boötes. It is also known as Caldwell 45. The Caldwell catalog holds visually interesting celestial objects that are not as commonly observed by amateur astronomers as the more famous Messier objects.

NGC 5248 is one of the so-called ‘grand design’ spirals, with prominent spiral arms that reach from near the core out through the disk. It also has a faint bar structure at its center, between the inner ends of the spiral arms, which is not quite so obvious in this visible-light portrait from Hubble. Features like these which break the rotational symmetry of a galaxy have a huge influence on how matter moves through it, and eventually its evolution through time. They feed gas from a galaxy’s outer reaches to inner star-forming regions, and even to a galaxy’s central black hole where it can kick-start an active galactic nucleus.

These flows of gas have shaped NGC 5248 in a big way; it has many bright ‘starburst regions’ of intense star formation spread across its disk, which a population of young stars dominates. The galaxy even has two very active, ring-shaped starburst regions around its nucleus, filled with young clusters of stars. These ‘nuclear rings’ are remarkable enough, but normally a nuclear ring tends to block gas from getting further into the core of a galaxy. NGC 5248 having a second ring inside the first is a marker of just how forceful its flows of matter and energy are! Because the galaxy is relatively nearby, its highly visible starburst regions make the galaxy a target for professional and amateur astronomers alike.

Sail Along with NASA’s Solar Sail Tech Demo in Real-Time Simulation

Sail Along with NASA’s Solar Sail Tech Demo in Real-Time Simulation

Unable to render the provided source

NASA invites the public to virtually sail along with the Advanced Composite Solar Sail System‘s space journey using NASA’s “Eyes on the Solar System” visualization tool, a digital model of the solar system. This simulation shows the real-time positions of the planets, moons, and spacecraft – including NASA’s Advanced Composite Solar Sail System.

Solar sails use the pressure of sunlight for propulsion, angling toward or away from the Sun so that photons bounce off the reflective sail to push a spacecraft. This eliminates the need for heavy propulsion systems and could enable longer duration and lower cost missions. The results from this technology demonstration – including the test of the sail’s composite boom system – will advance future space exploration to expand our understanding of our Sun and solar system. 

The Advanced Composite Solar Sail System, which launched in April 2024, and deployed its reflective sail in August, is currently orbiting approximately 600 miles (1,000 kilometers) above Earth and is frequently visible in the night sky to observers in the Northern Hemisphere. Fans of the spacecraft can look for the sail in the night sky using a new feature in the NASA mobile app. Visibility may be intermittent, and the spacecraft could appear at variable levels of brightness as it moves in orbit.

For more mission updates, follow NASA’s Small Satellite Missions blog.

NASA’s Ames Research Center in California’s Silicon Valley, manages the Advanced Composite Solar Sail System project and designed and built the onboard camera diagnostic system. NASA Langley designed and built the deployable composite booms and solar sail system. NASA’s Small Spacecraft Technology (SST) program office based at NASA Ames and led by the agency’s Space Technology Mission Directorate (STMD), funds and manages the mission. NASA STMD’s Game Changing Development program funded the development of the deployable composite boom technology.
