Building The World’s Most Powerful Satellites w/ Will Marshall | EP #90

In this episode, Peter and Will dive into satellite technology, what it takes to create a company like Planet, and its effect on ecosystems across the world.

Will Marshall, Chairman, Co-Founder, and CEO of Planet, transitioned from a scientist at NASA to an entrepreneur, leading the company from its inception in a garage to a public entity with over 800 staff. With a background in physics and extensive experience in space technology, he has been instrumental in steering Planet towards its mission of propelling humanity towards sustainability and security, as outlined in its Public Benefit Corporation charter. Recognized for his contributions to the field, Marshall serves on the board of the Open Lunar Foundation and was honored as a Young Global Leader by the World Economic Forum.

Unveiling the formation of the first galaxies

Utilizing high-resolution three-dimensional radiation hydrodynamics simulations and a detailed supernova physics model run on supercomputers, a research team led by Dr. Ke-Jung Chen from the Institute of Astronomy and Astrophysics, Academia Sinica (ASIAA) has revealed that the physical properties of the first galaxies are critically determined by the masses of the first stars. Their study is published in The Astrophysical Journal.

Equities, news and trading rules

Can a computer therefore replicate the way a discretionary trader reads the Financial Times, to harvest alpha from the FT?

This research demonstrates how equity traders can use machine-readable FT news articles to create systematic trading strategies for large-cap US stocks.

Gaia maps largest ever collection of quasars in space and time

Astronomers have created the largest yet cosmic 3D map of quasars: bright and active centres of galaxies powered by supermassive black holes. This map shows the location of about 1.3 million quasars in space and time, with the furthest shining bright when the Universe was only 1.5 billion years old.

The new map has been made with data from ESA’s Gaia space telescope. While Gaia’s main objective is to map the stars in our own galaxy, in the process of scanning the sky it also spots objects outside the Milky Way, such as quasars and other galaxies.

The graphic representation of the map (bottom right on the infographic) shows us the location of quasars from our vantage point, the centre of the sphere. The regions empty of quasars are where the disc of our galaxy blocks our view.

Everest-sized ‘Devil comet’ tonight: How to see the once-in-a-lifetime 2024 event

As we speak, the comet 12P/Pons-Brooks (Pons-Brooks, for short) is making its way around the inner region of the Solar System for the first time in more than 70 years – and might soon become visible to the naked eye.

At approximately 30 kilometres (19 miles) across, this giant icy lump is comparable in size to Mount Everest, says astrophysicist Dr Paul Strøm, and is “one of the brightest known periodic comets”

A Halley-type comet, Pons-Brooks completes its journey around the Sun every 71.3 years and was last spotted in our skies in 1954.

Scientists Find ‘Switch’ That Stops Immune System Attacking Healthy Cells

Our immune system is talented at telling the difference between the chemistry of our own body and that of an invading pathogen. When it malfunctions, our body can become host to an intense civil war.

Scientists are keen to understand this in more detail, and a newly identified ‘switch’ that deactivates a sensor of foreign DNA may provide important insight.

A key part of this discovery, made by a team from the Swiss Federal Institute of Technology Lausanne, is an enzyme called cyclic GMP-AMP synthase (cGAS).

Israeli researcher awarded IEEE medal, the Nobel Prize of engineering

Prof. Hagit Messer-Yaron from Tel Aviv University (TAU) is the recipient of the 2024 Institute of Electrical and Electronics Engineers (IEEE) medal for Environmental and Safety Technology for outstanding accomplishments in the application of technology in the fields of interest of IEEE that improve the environment and/or public safety. The award consists of a bronze medal, certificate, and cash honorarium.
