    Before the Big Bang

    Harvard researchers are proposing using a “primordial standard clock” as a probe of the primordial universe. The team laid out a method that may be used to falsify the inflationary theory experimentally.

    Stars in the making

    A paper authored by Harvard’s Eli Visbal with colleagues from the California Institute of Technology and Tel Aviv University suggests that it may be far easier than commonly thought to peer deep into the universe’s history and observe the telltale signs of the formation of the first stars and galaxies.

    Get ready, think big

    Ten of Harvard’s great minds gathered at Sanders Theatre on Thursday (Feb. 17) for the second annual Harvard Thinks Big, a student-organized discussion in which 10 speakers each took 10 minutes to explore a topic near and dear to their hearts.

    From the cosmos to the cell

    A conference at the Radcliffe Institute for Advanced Study examined the prevalence of patterns in the natural world, from enormous ones that order the cosmos to cellular and molecular patterns in living things.

    Building a stellar time machine

    Harvard researchers are building a celestial time machine that lets astronomers look back at hundreds of thousands of objects in the Earth’s skies over the past century.

    Physics for musical masses

    Harvard physicist Lisa Randall is taking Paris’ operagoing public to the fifth dimension this month, working with a composer and artist to present an opera that incorporates Randall’s theories about extra dimensions of space.

    Life in the universe? Almost certainly. Intelligence? Maybe not

    We are likely not alone in the universe, though it may feel like it, since life on other planets is probably dominated by microbes or other nonspeaking creatures, according to scientists who gave their take on extraterrestrial life at Harvard last week.

    Solar system’s twin has two asteroid belts

    Astronomers have discovered that the nearby star Epsilon Eridani has two rocky asteroid belts and an outer icy ring, making it a triple-ring system. The inner asteroid belt is a virtual twin of the belt in our solar system, while the outer asteroid belt holds 20 times more material. Moreover, the presence of these three…

    NYU chemist Robert Shapiro decries RNA-first possibility

    Back in the depths of time, an event almost miraculously improbable happened, creating a long, unlikely molecule. And life arose on Earth. Or, if you prefer, back in the depths of time, in a soup of small, relatively common molecules, an unknown chemical reaction occurred, sustained itself, replicated … and life arose on Earth.

    Black holes are the heart of galaxies

    Astronomers think that many — perhaps all — galaxies in the universe contain massive black holes at their centers. New observations with the Submillimeter Array now suggest that such colossal black holes were common even 12 billion years ago, when the universe was only 1.7 billion years old and galaxies were just beginning to form.…

    Star quest knowledge provides new view of ourselves

    In a basement laboratory at the Harvard-Smithsonian Center for Astrophysics (CfA), surrounded by instruments built to detect the universe’s distant secrets, sits a machine that will help us look not outward to the stars, but inward at our own bodies.

    CfA reveals Magellanic Clouds are first-time visitors

    The Large Magellanic Cloud (LMC) and Small Magellanic Cloud (SMC) are two of the Milky Way’s closest neighboring galaxies. A stunning sight in the southern hemisphere, they were named after the Portuguese explorer Ferdinand Magellan, who explored those waters in the 16th century. For hundreds of years, these galaxies were considered satellites of the Milky…

    Can science, religion coexist in peace?

    Almost 14 billion years after the big bang, and 3.5 billion years since the first bacteria appeared on Earth, humans occupy just one branch of the tree of life. We share an evolutionary limb with other eukaryotes, creatures whose membrane-bound cells carry genetic material. Our biological neighbors developed over time just as we did, by…

    Measuring one of the universe’s building blocks

    Only a few people think deeply about electrons. One is Gerald Gabrielse, Leverett Professor of Physics at Harvard University. In the past 20 years, he has discovered new things about them, things that even Albert Einstein never knew. And he’s trained a half-dozen young Ph.D.s in the business of how subatomic particles make the universe…
