Today is a big day for me.

I have been lucky enough to have had many big days in my life.

Standing in line with my parents as they cast their votes in the election that would bring apartheid to an end and see Nelson Mandela elected president of South Africa.

Standing on an escalator as it took me down to baggage claim after arriving in New York City. Not as a visitor, but as an immigrant.

Standing at a podium to deliver the commencement speech when I graduated with my PhD.

Standing at the White House for the first time as someone who had actually been hired to work there. (I know. Crazy!)

But when I think about what has made my life SO extraordinary, I come back time and again to the people I have been incredibly fortunate to cross paths with.

Which brings me to today.

Because today, I am standing before you... (ok, just kidding :)

Today, I am launching a new podcast called alpha (@alphaXpodcast).

Over the years, I have sat across from extraordinary women shaping the future through sheer brilliance and fortitude. Women leading research, building companies, shaping policy, advising presidents, and carrying more than most people will ever see.

Again and again, I have walked away from those conversations inspired, humbled, and deeply grateful.

alpha is my way of sharing those conversations with you.

It is a podcast about women shaping the future through science, technology, and discovery, and redefining what leadership looks like along the way.

Conversations with astrophysicists and marine biologists, cancer researchers and glaciologists, quantum physicists and biotech founders.

But not just the polished story. Not just the breakthrough, the award, or the job title. The choices that shaped their careers. The rooms that tested their voices and the people who challenged them. The failures, risks, reinventions, ambitions, and turning points that rarely make it into the official story, but shape everything that comes after.

I could not imagine a more powerful first guest than Gretchen Goldman, PhD, President and CEO of the Union of Concerned Scientists (@UCSUSA). Our conversation explores what happens when evidence becomes inconvenient, what it takes to defend science, and how we hold onto both courage and humanity when stakes are high.

I left that conversation feeling hopeful for our future, because people like Gretchen are working every day on behalf of all of us. I believe you will too.

I want to thank Valentina Bojanini, @dmbalarezo, @tylercowen, and my producer, @melaniescroggs , who helped shape alpha and bring it into the world. I am deeply grateful to all of you.

So today, I actually do find myself standing at another beginning. And this time, I get to bring all of you with me!

The Project Sunrise @Airbus A350-1000ULR has touched down in Toulouse, France after completing a 24 hour 24 minute non-stop flight from Melbourne, Australia.

The aircraft flew northeast over the Pacific, over the US and Canada, then across the Atlantic and south over the UK to Toulouse, crossing three continents and two oceans, with two sunsets and two sunrises along the way.

My hands are sweating..😅 Nina Caprez somehow makes the impossible look... CALM.

Back in 2011, she became the first woman to climb Silbergeier, a legendary 240-meter, six-pitch route in Switzerland's Rätikon range. It's known for its tiny footholds, razor-sharp holds, and long runouts where every move has to be absolutely perfect.

This is what years of training, patience, and complete trust in your own movement looks like

Wilson’s Storm-Petrel. Never seen one of these cool birds. They hang out with the whales.

This app is fantastic!

[Cory Mottice @EverythingWX]

The EverythingWeather app was built to showcase the incredible amount of data produced by NOAA and the National Weather Service and to make the NWS forecasts and products easy to access and digest.

The app includes over 200+ products/data sources and more is constantly being added. There is data from the NWS · SPC · WPC · RFC · AWC · CWSU · NHC · CPC · NDBC · USGS · NCEI · SWPC, and now even ECCC.

If you really want a deep dive into all the products, take a look at the attached image (you'll have to zoom in!) and if you haven't checked out the app yet, the newest version is out now for iOS and will be soon for Android!

The @USCG Eagle docked in the Old Port tonight as a large tanker ship leaves the harbor. The Eagle sits so still on the water; this was a 3 minute, 10 second exposure and the ship isn't blurry at all.

that first move would've never crossed my mind 🤯

[The English Oak Project @TheKentAcorn]

Blenheim Palace has 1,000 veteran oaks (over 400 years old) The oldest is over 1,000

Deer Parks, Castles & Royal Estates have the majority of England’s ancient oaks

These private estates are the reason England has more than the rest of Europe combined

William Nicholson painted the small fishing village of Shingle Street which stands at the south end of Orford Beach in Suffolk in 1908. On the left can be seen a Martello Tower and a cluster of fishermen's cottages around the Life Boat Inn, the white, gabled building.

The sheer amount of energy it takes to defeat gravity is humbling, but a powerful reminder of what humanity is capable of.

My photography is to hopefully provide an optimistic perspective of humanity's future among the stars.

Edward Hopper made his first visit to Paris in 1906, boarding at 48 Rue de Lille, depicted here. He painted frequently outdoors and fell in love with the city and its culture: 'I do not believe there is another city on earth so beautiful as Paris.'

'A Morocco Street Scene,' (1880) is quintessential John Singer Sargent in its dynamic use of angles and fascination with how direct and indirect light reflects onto and off white surfaces set against an intense blue sky.
