They were formed in supernovae.
Heavier elements are formed from hydrogen, the most abundant element in the universe, through a process called nuclear fusion. There are machines or structures in the universe that do this, and we call them stars. It is the process within stars, stellar nucleosynthesis, that allows heavier elements to be created up through iron. Elements heavier than iron are formed in supernova events.

Elements heavier than hydrogen are formed through nuclear fusion processes in stars. When lighter elements fuse together in the intense heat and pressure within a star's core, they can form heavier elements. This process continues throughout a star's life until elements up to iron are created. Elements heavier than iron are formed through supernova explosions or in the collisions of neutron stars.
Heavier elements are formed through nuclear fusion processes that take place in the core of a star. Hydrogen atoms undergo fusion to form helium, and then this process continues to create heavier elements by fusing helium atoms together. As the star fuses lighter elements, it produces heavier elements through a series of nuclear reactions.
Most of the other elements were formed in the cores of stars through nuclear fusion processes, while some heavier elements beyond iron are created in supernova explosions. These processes involve the fusion of lighter elements into heavier ones under extreme temperatures and pressures.

a series of star cycles
The heavier elements in the universe were primarily formed through processes such as stellar nucleosynthesis and supernova explosions. In stars, nuclear fusion combines lighter elements like hydrogen and helium into heavier elements up to iron. Elements heavier than iron are typically formed during supernovae, where the intense energy and neutron capture processes create these elements. Additionally, some heavy elements may also form through the merging of neutron stars.
Elements heavier than iron are formed through processes like supernova explosions, where the intense heat and pressure create conditions for nuclear fusion to occur, leading to the synthesis of heavier elements. This process is known as nucleosynthesis and is crucial for the creation of elements like gold, uranium, and beyond in the universe.
Chemical elements are formed in the Universe by stellar nucleosynthesis.
Elements heavier than iron are formed in super-nova explosions.
Elements in the universe are primarily formed through nuclear fusion in stars, where lighter elements fuse to create heavier ones under extreme temperatures and pressures. During their life cycles, stars produce elements up to iron through fusion; heavier elements are formed during supernova explosions when massive stars collapse. Additionally, the Big Bang nucleosynthesis created the lightest elements, such as hydrogen and helium, shortly after the universe began. Overall, these processes contribute to the diverse elemental composition found throughout the cosmos.

Once the Universe got cold enough, atoms could form. It is believed that in the Big Bang, only hydrogen, helium, and small amounts of lithium formed; all heavier elements were formed later, through fusion in stars.Once the Universe got cold enough, atoms could form.

a series of stars
Hydrogen and helium were formed shortly after the creation of the universe (when the protons and alpha particles combined with electrons). Everything else was formed within the core of stars (by fusion reactions).
